Tofficu4pcs Trolley Tokens Key Ring Shopping Trolley Tokens Keychain Release Token Coin Keyring Small Quarter Holder Keychain for Grocery Shopping Cart

It was exactly what I was looking for and it works. Will not break like the plastic one I had. The extra ones that made it easier so that I can give one to my employees

There was no review or info on if they was supposed to work for loonies or quarters. I found out the hard way it's not for carts that require a loonie. These are for quarters only.
