A super strong magnet with a keychain and a bison. This magnet allows you to hang the bison on a magnetic surface, as shown in the pictures.

The bison comes in a random color. If you only want to buy the magnet with the keychain, you can do so under the "accessory" category.
 
It is also possible to add a log strip of the type "Wider micro log strip RITR" which is water-resistant and fits perfectly in bisons.
