ink mop

And ink mop is a handmade graffiti marker. It's designed to make wide graffiti tags that drip ink. The most common ink mop would be the NYC Mop. It's normally made with an empty deodorant container...then ink is added and the tip (nib) is made from a strip of felt, like felt from a chalkboard eraser. These markers originated from New York City, during the graffiti epidemic on the New York City subways.

I bombed the entire subway car with my graffiti tag, using my ink mop.
