is it a magic marker? it erases or change the color of the other markers? just guessing....
Who knows I would try it, but they have a dried out a little too much to work Damo
or a drop of alcohol..that loosens the ink
I got my first color set this week from ebayIt is more of a jumble rather than a set, but it came with the pens which I most wantedDoes anyone know what the blue pen does, and why it has a blue lid? Damo
