Waterman Fountain Pen Ink Cartridges Long Mysterious Blue 8 Count

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.

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

It’s original, however I did not fit in my pens. Apparently they don’t produce the same size. So I am just gonna buy a new pen so I can use these.

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.

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

THE WORK GREAT IN MY FOUNTAIN PEN. GOOD CHOICE............

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

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
