Since its launch in 2007, the Platinum Preppy fountain pen series has grown in popularity among a wide range of age groups around the world. The all new Platinum Prefounte is a model designed more for adults that boasts a sense of high quality while retaining the basic functions of Preppy fountain pen. Subdued colors are employed for the transparent body made of resin. The graphics are also kept simple, while the metal clip adds an accent to produce a chic, translucent appearance ideal for adults. The stainless steel nib features a welded tip made of an abrasion-resistant special alloy, which provides an excellent writing feel.

The Prefounte fountain pen is equipped with Platinum's “Slip & Seal Mechanism” that prevents ink from drying out in the pen with the cap on for one year. It accepts proprietary Platinum ink cartridges (one blue-black cartridge is included) or a Platinum converter (sold separately) to fill with bottled ink.

For those who seek a smart and casual fountain pen, the Prefounte is ideal for both business and daily use, as well as for fountain pen beginners.

By converting this pen to an eyedropper, you can fill the entire barrel with ink for maximum ink capacity! All you need to do is add an o-ring and a small amount of silicone grease to the threads (available separately).

Very smooth writer

I love this pen. It's cheap but looks good so I plan to add other colours to my collection. I love how it writes very smoothly.

What a great find!

I love this pen! I like the profile of Prefounte vs Plaisir, with Prefounte's flat edges compared to Plaisir's rounded (just a style preference), though I have both. The F nib I ordered writes beautifully, and I enjoy the snap cap. The only 'drawback' for me is that my other pens are more substantial in weight so it's a little adjustment with this very light plastic pen. GREAT quality for an inexpensive way to have intro to fountain pens. It's a good purse/work pen where if it gets lost/dinged, I won't be crushed

great pen, EXCELLENT customer service

[updated] Great pen! I bought it for eyedropper fill and didn't know about the required conversion, so my first attempt leaked horribly and I left a 1 star review. The company saw my struggle, emailed me, had a real, human, non-boiler-plate interaction, and helped me understand what this noob was getting wrong! What excellent customer service!! After watching the videos they linked and converting, I now have two of these pens in different colors and I couldn't be happier.

New Daily Pen

I love this pen! It's become my daily pen now, the medium nib is perfect for me, the only downside I have found is that storing it nib down sometimes causes ink splatter upon opening. Honestly that just means that I can store it upright and not worry about a hard start. The body and cap being plastic works well for me because I can post the cap on the end and it won't weigh the pen down on the back while writing.

Disappointed

I've had a lot of problems with flow with this pen and, in fact, all the preppys too. Frustrating.

Excellent Pen and Great Value

I have been very impressed with Prefountes. I have both the fine and the medium. Excellent writers that don’t dry out. The snap cap makes them convenient for quick notes on the go or outdoor sketching. A great value! I always have one inked up, right beside my expensive gold nibbed pens that cost many times as much.

Pen with more weight

First time handling a fountain pen. Feels heavier than a normal pen and writes differently. I won't say worse, but I'm curious how this feels compare to normal pens.

I rate this medium because the feed is just sluggish to me

I rate this medium because the feed is just sluggish to me. Maybe the ink cartridge is the problem. The ink is a faint blue and feed does not keep up at times. Not exactly as desired. Rest of pen is great: feel, fit and finish, balance. Just did not feel like my Preppy.

Great pen with a smooth nib. Perfect work pen for the price point if you want something quick and reliable.

Wow!

For a cheap pen, this writes better than some of my $100+ pens. It's really smooth with no skips or hard starts. The slip and seal cap is a bonus allowing the pen to start right away. The converter is a must, but it's daylight robbery how much Platinum wants for it.

Great, affordable pen

Great daily writer with medium nib that is relatively smooth. I really liked that it came with Blue- Black ink rather than plain black.

0 for 2

I bought two of this pen. One several years ago when they first came out and another one recently in 2024. Both times it was the same experience. The pen would hard start almost every time uncapped and while writing. The first time the pen dried up completely after only a few weeks of being set aside. The second time I got so fed up with it I threw it away. I also bought a Procyon and a Desk Pen and they have ALL acted the same. The only Platinum pens I have ever had work for me are the Preppy. I really want a 3776 but there is no way I can risk this type of quality and experience with such an expensive pen.

Cheap pen, cheap thrills

I thought this pen was going to be better than what most were saying. It is not as enjoyable to write with as my Prera, Kakuno. this seems to write slower. I opened the tines and still not flowing very heavy. Maybe it is the cartridge and may need to fill the body up with ink, but I would be scared it might get crushed being a cheap plastic instead of a heavy resin or metal. And the converters are too expensive to buy separately which shocks me. My jinhaos come with a converter, why can't these for a low end pen? I am not extremely thrilled with this pen but will use it if I get a shimmering ink for a pen I don't mind if it gets clogged with pigmented ink. Time will tell.

Platinum Prefounte Fountain Pen - Night Sea

This is my 2nd one, bought because I love the first one so much and wanted one to carry w/ me!

good everyday pen

I bought this pen for the gorgeous color and because Platinum cartridges hold a large amount of ink. I've had one Platinum Preppy before this which I've lost track of but it was very much the same model without this dress. It is meant for daily, continuous use and it's perfect for regular loose-leaf paper with its Fine nib. Once i get going i forgive the dry start because it runs so smoothly. I dislike the hard and loud snap cap but it trains me to be mindful of capping too often, unnecessarily, before I've finished all my writing business. So it enables me to be more efficient in a writing session.

Puts way more expensive pens to shame.

Platinum has nailed the colors and styling of the Prefounte series. This pen punches way above its price range. The pen is small and light weight, but still offers a good grip. The styling, colors, price and features of this pen makes you wonder why bother with Sailor Pro Gears and Platinum 3776. I hope Platinum will release a extra fine (0.2mm) version of the Prefounte series. It's not a big deal to swap a 0.2mm nib from a preppy, but still.

Great value

I was surprised at how well this pen writes. Very smooth light weight pen. Beautiful color, caps securely which is a major selling point for me. This is a great pen for anyone just starting out with fountain pens without spending a lot of money. I purchased the Night sea and Deep Emerald colors, both are lovely! I'm currently using a converter in the Deep Emerald pen with Diamine Azure ink.

Good pen, of course!

This is my second Prefounte and it inks up and writes smoothly like my first one. I've found this Plantinum pen to be an elegant workhorse and highly recommend it.

Wrote great until it didn't.

I have a medium nib Prefounte that writes well, with wide wet lines. So I ordered this one to try a 'Fine' 0.3mm nib. It had a very hard time losing ink from the included cartridge so I flushed it out and tried again. After,the flush it worked well though a bit scratchy at first. This subsided and it smoothed out and did a good job for a few days. Now it mostly doesn't write. Not a big loss, but I'm finding the Platinum nibs seem to have more problems than I want to deal with. Of two Procyons, one (F) has never smoothed out. The Med is fine. So, 3 stars because half of them are good pens.

Pretty pen

I am very new to the fountain pen world. This was a last minute throw in the cart to get free shipping decision. The pen is a pretty night sea color of blue. It's lightweight (which I love) and writes very smooth. Sometimes it doesn't flow as smoothly as I'd like but a little shake and all is well. Because I threw it in last minute, I didn't realize it was a proprietary cartridge. I found a converter and am looking forward to using some pretty, fun ink colors when the cartridge is empty. But I even like the blue/black cartridge that was included and I am not a black ink kinda gal--the saving grace is that it's more blue than black. I would definitely purchase another one of these pens, especially at this price point.

Uptown Preppy

Nice pen, not sure it was worth the extra cost as it is essentially a just a nicer Preppy. Color (Night Sea) truly is a beautiful color, though. The fine nib hard starts after sitting uncapped for a short time, but writes quite well otherwise.

excellent--very soft nib tho

I bought 2 of these to use at work, so that I wouldn't be too mad if they wandered off. This was the first Platinum pen I had ever used, (coming mostly from Kawecos and TWSBIs) and I am a heavy-handed writer. Unprepared for how soft the nib was, I promptly sprung the tines beyond function (100% user error on my part). Fortunately I had bought two! It's a very nice pen for the money, if you are prepared for the nib, and a little more professional looking than the Preppy.

Favorite starter pen

Comfortable to use and writes so smooth. The cap keeps the nib wet forever. The price point means I keep it in my work bag without worrying about losing it someplace. I have kept this pen inked since I bought it.

Upgraded Preppy

A great writer. Very smooth and best yet, it's syringe loadable. So is the Preppy but I have two of those that developed hairline cracks in the barrel. Not fun when you load with a syringe.

This pen is so nice to write with. Smooth and the overall performance is flawless. It's not a pen you have to fuss with and worry about. I keep it full of any ink that looks like the sea at night.

Not Great

Lighter and cheaper feeling than I expected. And it sometimes runs dry on me.

It's as good value as one can expect for the price. It seems to be a decent writer, although it might display some skipping tendencies over longer text. I feel there are some consistency issues while writing longer texts.

Frequently Asked Questions

How do I fill this fountain pen from an ink cartridge? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

A cartridge is small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write!

This pen uses proprietary Platinum ink cartridges, which are available in a few colors.

You can learn more about how to actually install an ink cartridge on our blog, or in this video tutorial:

How do I use a converter? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

A converter goes in the place of where the ink cartridge would normally go. From there, you can fill your fountain pen from bottled ink.

A converter is a detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter.

We have a great video showing how to use a converter here:

How do I clean this fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It mostly comes down to flushing out the pen with water, and sometimes a little bit of pen flush if the ink is really stuck. 

We put together a blog post with step-by-step instructions, or you can watch the video here:

We recommend a good cleaning every 2 weeks, and any time you change ink colors. Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.

For even more information about fountain pen cleaning, check out our Fountain Pen 101 video blog post.
