These are double sided music staff lap boards! There is a print of music staff lines printed on one side and the reverse side of the board is a plain white dry erase writing surface.
9" x 12" x 1/8" thick with a really nice set of 3 music staffs which are protected with exclusive clear dry erase writing surface for years of trouble free use. For added comfort and safety the lap boards come with smooth rounded corners and edges and they're light weight and small enough for any young student.
Comes with a dry-erase marker and eraser.
