Works great on black wheels, hardly comes off when washed.

Good marker for ink refills, the best in my opinion it doesn’t leak or drip too much w less dense ink, the only reason your gonna get rid of it is because you loose it or because you loose it, it’s overall the most reliable out of all the 8mm nibs I’ve tried

Love Uni markers. My favorite vandalizing tool. :) bring them with me everywhere and keep it on me all the time. It’s my go to marker.
