Poster/Chart Display Holders are lightweight, yet durable core board that's covered with a clear film protector held in place by velcro strips on the inside surface of black frame borders. Simple to use! Just peel back the clear film cover to insert or remove graphics or exhibits over and over again. Save the cost and the hassle of dry-mounting your display and exhibits on foam board. Two-sided Display Holders are also available. Use Dry-Erase Markers on clear film covers to draw special attention to important aspects of your graphics or exhibits. Those markers simply wipe off the film! Poster/Chart Display Holders are so light, they're easy to transport and set up. Carrying cases are available.
