Mega 2021 Puzzle Cache

This is a remix of the Nickel Puzzle box and has been re-mixed to take a geocache magnetic micro.

I've done two versions one with the Lincolnshire Mega 2021 name and one without.

To complete the cache you will need a 4mm bead (I used children's Aqua Bead) and an M3 nut/bolt of 25 - 30mm length
