Favorite ink color

The Kaweko cartridge ink flows so well (smoothlly and evenly) from my new Kaweko fountain pen. It drys quickly, as well.

Nice color, good flow through my fine Nib on my Kaweco Sport

This Kaweco Royal Blue fountain pen ink is a classic grand blue. I highly recommend this cartridge ink color for those needing a blue ink in a cartridge.

Al way easy to put in pen and writes smoothly.

Great king lasting and quality ink cartridges.

I bought these to go along with the shark pens for penabling. The ink is a nice but nothing fancy blue. Nice flow. Just what I needed.

My first purchase from Goulet Pens, and I only bought a few ink cartridges to replace the ones that I have used, but the package included notes from the person packing the shipment and the owners, not mention a mini Tootsie Pop! I know that they were printed form letters, but the sentiment was too genuine to take for granted. I got a great customer service experience in a small brown envelope, and I'll be back!

The items were very high quality! They wrapping and care that is taken is obvious and appreciated!

I was looking for erasable blue ink cartridges, and found these to be exactly what I was looking for. The ink is a bit more viscous that what I used previously- it writes with a nice deep bluey-purple since it flows a little slower. It dries within seconds, but dots take longer. I find myself replacing cartridges when my pen starts to dry up, but there is still enough ink left in the cartridge for it to pool along the bottom when I leave it on the table. This ink bleeds a bit if it gets wet, but erases beautifully with an ink correction pen. The color is a bit more purple than the ink correction pen blue, but not enough to be frustrating. I would buy these again and if available, would definitely buy this ink for fountain pen converters.

I mainly use ink cartridges in my pens for convenience. This is a beautiful shade of blue. I am very delighted with this ink.

I purchased a pen, it was very cute and inexpensive, but didn't initially purchase ink. Oops! I reached out via Facebook to the customer service team and was suggested to me to try this brand. It is expensive, works flawlessly with my pen, and as always, I am satisfied and beyond impressed with my order from Goulet.

This was the first blue I ever bought. I love it. There is sheen on Rhodia, not a ton, but it's there. I've even got sheen on cheap paper. Shading is almost non-existant on any paper. There is nothing truly extraordinary about this ink. It's just your average royal blue. It's a fairly dry ink, not near as dry as Pelikan 4001, but drier than most other inks. I love it and will certainly buy again.

I'm very fond of a particular bottled ink, which doesn't come in cartridges. I spent years trying to find a similar ink in cartridges, and this Kaweco is it. I've used them for a couple of years now. It flows very well in several different pens, and is a nice, solid blue--not washed out, not purple, just a well-saturated blue.

One arrived leaking. The other 5 were inky but ok. I am going to avoid Kaweco.

I bought the Kaweco Royal Blue ink to go with my new Kaweco Brass Sport Fountain Pen and I love both. The Royal Blue is deep and beautiful and looks great on paper.

I got this cartridge in the case with my Kaweco Al Sport Aluminum. The converter I had did not fit the pen, so I decided to just live with the cartridge until I could get a converter that fit. I've been living with and loving the cartridge for a few weeks; by far the happiest pen accident ever! This is a plain blue, with nice if inconsistent darker shading on the bottom of a stroke. What makes this ink so wonderful is its performance on bad paper. I am left handed, so I tend to smear slow drying inks, but fast drying inks tend to feather on many papers. Not Kaweco Royal Blue! Even signing a receipt, this stuff dries in a second or two, and has excellent bleed and feather resistance with that in mind. There are more vivid blues, there are blues that shade better, but this is among the best I've seen for everyday utility.Highly recommend at least to try, especially given the very low price!
