Make sure you never lose your way again, attach a tyre compass to your keys...Some of these work accurately, some need to have the compass needle re-magnetised with a neodymium magnet (hopefully this will work).
But, as we all have compases on our phones now..these could just as happily function as vintage novelty keyrings to impress your friends with.
The display cards they come on are pretty special top "Always First with the Unusual"
So I'm selling 2 complete cards of 12 keyrings for those of you who appreciate such things, and then some individual keyrings too.
