What kind of marker pen shall we use for Led Writing Board?

Common erasable marker pens can write/draw on this LED Writing Board, but their ink does not allow light to transmit to produce bright neon effect. We suggest using our special marker pens, which contain a fluorescent powder in the ink. When LED writing board is light, the drawings/word will be sparkling.
