WatermanFountain Pen Ink Cartridges, Long, Mysterious Blue, 8 Count

My favorite color ink for my fountain pens. Very unique and looks pretty on the page.

It's a dark blue colored ink that is comfortable for me to read. It writes smoothly. Waterman Ink cartridges are relatively large and last a good while. Just remember, as a "washable" ink you need to make sure not to drip water, coffee, etc on your page.

Blue black is my favorite color and I have had such a hard time finding cartridges. At last.

These cartridges work great. They are easy to install and fit perfectly in my pen you must remember to push it in the nib from the little dark blue/black bump firmly they screw the top back on. The ink dries quickly and will flow immediately if your nib is clean.

Nice to be able to use my pen. Great refills.

It's ink. Not sure what more you can say. I have to sign a lot of documents so I always choose blue ink, and this blue is very clear, vibrant and smooth. Really stands out on paper and this is my go to refill for all of my fountain pens.

Great refills for my Waterman fountain pen. Great value for your money it comes with 8 refill cartridges so I bought 2 of them i I write lots.i highly recommend this product to anyone

Very dark blue, fast drying, no clogs or bleeding.Great for my left-handed writing. No ink on the side of my hand.
