This model is a 4x4 Turbo Diesel key ring / key chain!

This keyring is 7.5cm wide, 3.1cm tall and is 6mm thick.

Keychains are designed with a 'channel' to allow for a 2.4mm (or smaller) ball chain to be looped through. Ball chain is available very cheap online in a variety of colours - we suggest cutting the ball chain to a length of approximately 15cm.
