lol last time i was filling up my flow pen.haha and all ink went all over my hand and inside my nail it's a black dot and i can't take the ink out..my whole hand was coverd in ink..and the counter was worse it came off the counter though but my hand was just pitch black..took me a while to get rid of it..and the marker was only half filled the rest went to my hands and counter..not i only have half a tint left :(
