The Movable Rod and Piston Keychain is scaled down from an actual rod and piston. The total length is just under 1 inch long, with a diameter of the piston just under 1/2 inch. The detail is amazing, and the piston moves just like the real deal. It comes with a keychain loop, but can be taken off the keychain and worn as a pendant as well.
