Pentel Brush Pen Cartridges, Black Ink, pack of 3 (Japan Import) [Komainu-Dou Original Package]

The ink works great and is waterproof/smudge proof which is perfect for inking line art before coloring with other mediums.

Love them

Just what I ordered

I have more pictures of the drawings i made with this ink but i feel like these are enough. Not really a pro when it comes to using the pentel brush pen but it's fun. This came with 3 ink cartridges so its a good purchase.

I didn't think they would last long. And, to be fair, they really can't. It uses a lot of ink to paint, really. I am pleased with them, given the givens. And I don't think it is unfair that they do get used up so quickly. It is just... physics, the way things are. I would purchase these again. And probably will in the future, as projects come up. They are even fun to write, or... paint... with. Not something I get to use every day. They can begin drying a bit. Just a bit of tinkering will fix it, until it is out of ink. I suppose there may be a way to refill it, I just doubt if the trouble would be worth the hassle and extra expenses involve. ymmv.

easy to use and long lasting

These are a good price, though it could be a little spendy if you use a brush pen a lot. I bought a few of these for backups, but I'll probably refill the ink with a syringe to save money.

Great ink that flows well and seems to be lightfast. Very dark although I’ve seen darker. Dries fast on certain papers...pair different papers to see which one you like. I believe hot-pressed paper will dry slower.

good!
