You've heard of Dry-Erase, but what is Wet-Erase? Although Dry-Erase is more common, Wet-Erase Boards also have their applications. Usually on a black surface, Wet-Erase pens create brighter, more vibrant and visible messages that don't smudge like dry-erase. They're especially good for shops and restaurants to post their specials. Wet-Erase Boards clean up easily with a damp cloth.
