Simply place items on the Smead Justick by Smead white board and they stick without using pins, magnets or tape. Each whiteboard solution has a clear overlay, so grab either dry or wet-erase markers and get to it. Write, display and interact with three times the benefit of a traditional board. Install 4 AA batteries into your board and watch the Justick surface technology transform the surface from zero adhesion into a powerful force field. Board Type: Dry-Erase Board Width: 36" Board Height: 24" Board Depth: 1".
