Isomars Waterproof Drawing Ink with Dropper – 35ml | Black India Ink for Calligraphy, Art, Technical Drawing | Fade-Resistant & Quick-Drying (Black)

The ink is pigment type similar to that of Uniball. You can do a simple eyedropper style conversation on the Pilot V7 cartridge types and get a super smooth writing light blue shades, waterproof pilot that will run for 100s of pages. Just ensure that the pen you do the conversation on is used regularly or else the pigments might clog the feed. !!Do not use in fountain pens!!

+This is dark waterproof ink. +Unfortunately if you don't refill your fountain pen daily, it will definitely dry and clog the pen. +Once clogged its very difficult to clean and restart the fountain pen. +Again it's ok for people who refils the pen daily like students but not for people who refils once in week.

I am new to using ink in my art and have only used it a couple of times, but I have found it of good quality. Ink flows smoothly, and the result after drying is great. Will buy it in other shades to experiment. Good product at a reasonable price.

Nice product. Dark black ink. Like it

This is the best black ink I used so far. The colour is pretty dark. I tested it out on a watercolor paper with a dip pen. I love the smoothness and richness of the ink. I saw some of the questions about filling it in a brush pen. I had a empty pental brush pen. Filled its cartridge with this ink. Now it is writing like when I bought it. The ink is indeed waterproof when it's dry. In case if you are wondering after watching the images, the paper I used is watercolor paper. The ink bled through when I wrote. Not when I poured water on it. I'm really happy with this ink. Hoping to buy their set of coloured inks in the future. Hope this helps!

Inks are good but on fabric the color seems to fade a little..after a wash.

It works

Very nice, easy to use. Helpful for nib work. I really liked it and would recommend it to the art lovers. Go for it.
