The Indoor Enclosed Dry Erase Board with Two Doors from United Visual Products lets you show your handwritten information without having to worry about someone erasing it. Write messages on the magnetic surface and secure them behind two lockable doors (two keys included) with full-length piano hinges and shatter-resistant windows. Choose a Radius-style or Traditional-style aluminum frame in a selection of sizes.
