The Noodler’s Boston Safety Pen is made of ebonite, a traditional material used for vintage safety pens. Safety pens are designed to help prevent any ink from leaking while capped. Unlike traditional fountain pens that seal around the grip when closed, the safety pen helps to create a seal right at the ink reservoir. They are not as vulnerable to pressure changes when traveling. They also start right up after periods of non-use due to the fact that the nib and feed stay submerged in ink when retracted. Please note that all Boston Safety pens will now come with a metal core made of surgical stainless steel.

When you first open it, you will notice that the nib is completely retracted into the barrel. To expose the nib, simply push and twist on the back of the pen, keeping the pen in a vertical position with the nib facing up. This is important! Otherwise the entirety of the ink supply will pour out of the pen. Slowly twist and push all the way up.

To fill this pen, retract the nib fully back into the barrel of the pen, and fill using an eyedropper or an ink syringe with no more than 1ml (to avoid overfilling and spillage).

To close the pen, you will need to retract the nib back into the barrel, keeping it vertical with the nib facing up, before screwing the cap back on.

We strongly recommend that you watch Nathan’s video below on best practices for using and filling this pen, as it is unlike anything else we carry.

It uses a #2 flexible nib, the same as the Noodler’s Nib Creaper flex pen.

The Noodler's flex pens were designed for the hands-on tinkerer - they are made to be taken apart and adjusted. The nib and feed pull right out and can be adjusted and heat set for optimal performance. Don't be afraid to get a little ink on your fingers while you learn how to use this pen.

As a simple rule of thumb for writing with a flex pen, just apply slight pressure on your downstrokes, which will spread the tines and increase the line width, achieving that optimal line variation. Make sure to go slowly so that the ink can keep up with your writing. As with any flex pen, it just takes practice!

Due to the residual machining oils used when cutting the feeds for these pens, we highly encourage you to give the pen a good flush before use. We recommend any of the following options: distilled water, water with a touch of dish soap, a pre-packaged pen flush, or a solution of 10% clear ammonia to water. This should resolve most ink flow issues!

My prized pen

Couldn't be happier with this pen. It can take almost any ink from India to acrylic etc and doesn't dry out. It works beautifully with a waterman 52 flex nib so now I virtually have a portable dip pen when I'm sketching on the go.

Great Pen, but Be Careful

This pen is great, I love the ebonite body. I switched out the nib for a Jowo and heat set the bib to the filler. It writes beautifully. If you're looking at a Boston Safety Pen, you are likely aware that you must carefully open and close the pen. Open it incorrectly and ink is everywhere, close it improperly and you risk damaging the nib. Thus, this is a great pen, but a word or warning to the owner.

The only modern safety pen on the market. Perfect for tinkerers.

There is a learning curve to writing with this pen, but once you get used to the extra steps writing is fine and enjoyable. Since there is only one white ink on the market for fountain pens, I bought this pen so I can use write with white dip pen inks and expand my options. Using non-fountain pen inks requires a lot of patience as you have to dilute the ink enough that it flows easily down the tube and feed. The semi-flex nib is underwhelming and railroads like crazy but can be replaced with other Noodler's nibs. Really wish there were nib options when purchasing this pen.

Unique and fun, but maybe not the most practical

The safety pen has some unique features. The nib retracts into the body to stay wet and in theory prevents the pen from leaking. However, this pen doesn't always live up to that. As Nathan notes in the YouTube video, sometimes uncapping causes a pressure change that causes ink to shoot into the cap and onto the threads, even if you're holding it upright. I don't experience this every time I uncap the pen, but when it did happen, it was messy. The other thing to note is that you must hold it upright to uncap it or you will spill ink out. Luckily, I've managed to avoid that so far. It is quirky to fill. You eye dropper into the barrel and very slowly draw the nib back up. Sometimes, the ink gets trapped above the nib and you have to carefully tap it to get some bubbles out. It's also very easy to overfill, making an unavoidable mess when you bring the nib back up. There are no markers or fill lines, etc., so you're going to have to wing it.Some good news for those who are concerned about Noodlers pens needing to be heat set is that I didn't have to do that with this one. The flex on this is not great and it is prone to hard breaking if you do much of it, which I wasn't expecting for a nib/feed constantly bathed in ink. The nib isn't the smoothest, but as a regular writer, it does just fine. It's a fun pen and I don't regret buying it, but it's definitely not going to be for everyone.

Overall a good pen

My first order with Goulet. As others have stated Goulet customer service is top notch A+. I received the chestnut safety pen and was wondering how I was leaving noodlers black finger prints on things. Turns out the pen was leaking. A quick interaction with customer service and a new pen was on the way and quickly. The pen. It's definitely a learning curve but overall works as expected. The only thing I'd say is you really need to disassemble the pen when switching inks to ensure it's fully clean before you make an unintended science project. Not too big of a deal but Nathan's explanation of using only your hands to take apart the pen might be accurate for subsequent tear downs but for the first one wow that thing is put together tight. Overall I'm quite happy. Very unique piece that's completely functional and very comfortable that works well. Try a sheening or shading ink. Wow, they pop! with what I would call a fine nib but wet enough for these types of ink to perform. I might need to heat set the nib for flexing. It almost immediately railroads with moderate line variation. It will do it nicely if the fees is primed but after writing for a while you really have to be patient to flex it.

FAQs about Fountain Pens

How do I fill a fountain pen with ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the pen's filling mechanism, which you can find in the Technical Specs section above. 

Here's a quick definition of the most common filling mechanisms:

  • Cartridge - A 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! Check out our quick guide here.
  • Converter - 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. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
  • Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
  • Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
  • Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking. Check out our video on how to use a vac filler here.

Check out more info on these filling mechanisms including a video on how to fill each one on our blog.

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

It depends on the filling mechanism, but it mostly comes down to flushing it out with water, and sometimes a little bit of Pen Flush if the ink is really stuck. 

It's a bit easier to show than to tell, so we've put together a few quick videos showing you the process:

How often do I need to clean my fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

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.

My pen won’t write! What do I do? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

First things first... make sure you have ink in the pen! Be sure that the ink cartridge or converter is seated properly in the pen, and that you aren't out of ink.

We always recommend you give your pen a good cleaning first, using our Goulet Pen Flush, or a drop of dish soap in some water. New pens often have some machining oil residue left in the feed, so a good cleaning often does the trick first.

If that still doesn't work, try priming the feed. This consists of either dipping your pen nib and feed in ink, or forcing ink from the converter down into the feed. 

If it’s still not working after that, please reach out to us so we can help! 

What's your return policy? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B
