Durable, masonite board offers a blank, ruled dry-erase surface on one side & rounded corners for more comfortable use. Each plain white board measures 9" x 12". The set also includes 30 pocket-style, dry-erase markers with bullet tips & 30 multipurpose, square felt / foam erasers (2") so each student is equipped a board, marker & eraser. Markers are AP certified nontoxic & conform to ASTM D-4236.
