If you've never seen these clocks before, your eyes will fool you. They look exactly like a tile, in fact even when you open the box you'll be sure they are ceramic. But pick one up and you'll be amazed. They are so light you can hang them on a push pin and unlike ceramic clocks, will never crack or break. The clock faces are made from prints of the original artwork, which are dry mounted onto foam board and sealed with a protective laminate. You'll receive a lifetime warranty on the movement. Requres one AA battery. Measures 6" square.
