shopping cart coin

I made my own shopping cart chip. It is very functional and versatile with a tab that facilitates pulling thanks to an ergonomic space for the fingers. There are three versions available that are very similar to each other (the result of tests to evaluate their resistance has proved, for me, all aesthetically appreciable):
Profile 1) overall length: 41.20 mm; finger insert: 2 mm;
Profile 2) overall length: 38 mm; finger insert: 1 mm;
Profile 3) overall length: 41.20; finger insert: 1 mm;
