ABSTRACT:
A pressure sensitive reusable writing board is provided which includes a backing member that includes an upper section that folds down over the lower section that accommodates the wax layer and polyester writing sheet. As a result, the upper section provides a protective cover for the lower section. A distal edge of one of the upper or lower sections includes a loop which is in registry with a slot disposed in the distal edge of the other of the upper or lower sections. As a result, when the board is folded together to assume a closed position, the loop may be folded forward through the slot disposed in the opposing section or panel and the stylus may be inserted through the loop to lock the board into a closed position. As a result, any writing or artwork made on the reusable writing surface can be preserved while the board is being transported or handled.
