Large ThoughtOnBoard is a 14″x18,” rectangular shaped dry-erase board with four suction cups, one in each corner, which assure the board is held securely to any smooth, glassy surface. A black marker, included, is secured to the back of the board with Velcro™. Like the small board, the large ThoughtOnBoard also comes with reversible suction cups, so you can use it in a forward orientation, for example by attaching it to other smooth surfaces like a stainless steel refrigerator door, Formica™, Plexiglas™ or sheet metal. Great for shopping lists, appointment reminders or as a memo board for stainless steel fridges. Great in corporate offices, restaurants, shops and stores to tell customers about daily specials, unique items, sales or holiday hours. FREE SHIPPING INCLUDED!
