A great way to point people in the right direction and get messages communicated. Extremely useful when positioned at school entrances and doorways. The standard writing surface is double-sided, Magna-White coated steel (uses standard dry-erase markers), and can also accept magnetic and/or static cling signage. The 18in. wide base should be weighted w/ water or sand for additional stability. All directional message signs are 65in. tall.
