The Ohto ceramic 0.5...
Verified Purchase
The Ohto ceramic 0.5 mm is possibly one of my favorite inks. So when I ordered this I expected the same quality, but a slimmer line. However, the ink flow was terribly inconsistent and never worked well. I'm not sure if it was just mine, but I regret going over to a 0.4.
