If your memory is like ours, it doesn?t exist. Solve the problem by writing your projects, errands, and ?honey-do lists? down on the BKG Chalkboard. It measures 12? w x 18? h making it easy to not only write on but read as well. Made of embossed aluminum with a special coating you don?t have to worry about breaking the slate?.and you should hear what fingernails sound like on this. Chalk and eraser not included (make a note to get some).
