#but a bottle of yatsumoto sumi (two ounces) is about 7 dollars

Sorry if this has been answered before, search engine on Tumblr sucks, but what do you use to ink :0?

oh yeah don't i know it—sometimes i try to find posts or asks ive answered and its like "youve never mentioned this word before in your life!" and i just. huaghgh.

anyway, the ink that I usually use is Dr. Ph. Martins Bombay India Ink, it's the only Completely waterproof black ink I'm aware of (and there's a variant called Dr. Ph. Martin's Black Star Matte which doesn't reflect light but it's more expensive) BUT when I do not want to pay a whole lot of money for a bottle of ink, Yatsumoto Sumi India Ink is much cheaper AND nearly waterproof. As long as you wait for it to dry, and don't scrub it too hard with a brush, it should be fine.
