Singapore supermarket trolley coin

Never hunt for a $1 coin to use a supermarket trolley again!

This fits perfectly in all local supermarket trolleys. It's discreet and hands nicely on a keychain (e.g. with your car keys) for easy use.

**Works on all trolleys that accept new SG $1 coins. For older trolleys that use old $1 or new 50c coins, consider the Trolley Coin Duo model found here:
