product info: ...
For the price of 12, you get 13 (a baker's dozen) stemless magnetic wine charms! Each of your friends can choose a different color, thereby alleviating the need to ask, "Is this my glass?"
IMPORTANT: These are not toys and should not be given to anyone who likes to put inedible objects into his/her mouth. Swallowing one magnet does not pose any health concern, but swallowing two magnets when they are not already attached to each other can be dangerous.
One magnate is securely attached to the back of the tile, and the other goes on the inside of your glass. These are Rare Earth Magnets and very strong. For example, if you were to use just the magnetic half with the tile as a refrigerator magnet, it could hold up a standard 8.5x11 piece of paper.
