The Cache is King Fridge Magnet would make a great item to put in a cache, to give to a friend geocacher, or to keep for your own fridge door.  Made exactly the same as our button badges but with the backing plate having a magnet instead of a pin.

We use traditional metal components in our Geo-fridge magnets, so what you get is a high quality fridge magnet that will last a long time. The only non-metallic components in our badges are the print of the design and a mylar plastic cover, everything else is metal.
