The area I want removed is 7 and 1/2" tall and varying in width from 5 and 1/2" on down. I want to keep the hand and pencil but remove all the other black, green, white, purple, and blue ink (see pics below). Do you think the white will oxidize or is picosure pretty good about taking care of that? What do you think a realistic price and realistic expectation of the number of required treatments would be? I hate myself so much for getting this and am really hoping for some good news.
