The "Trolly Coin" is your handy keychain tool that you can use for those expensive trolleys at Aldi and a few other smart shops. It has the dimensions of the $2 coin 20.5mm diameter and is 3.2mm thick. Prints well with any material and fits on keychain nicely!
There are two files and one is spelled Trolly, the other is spelled Trolley :)
Attach it to your keychain and place coin part in the shopping cart coin holder. Don't leave your trolleys lying around! Happy shopping :)
