The Caddy-Lock

With this tool you can unlock every shopping cart with a lock. (normally to be opened with a €1 coin.) The special shape allows you to retract the tool once the lock is opened! The small part can stay on your key-ring anytime. Also nice to help a person who hasn't a coin to unlock a shopping cart. You will make his/her day, and the smile in return will make yours!

Takes about 5' to print ;)
