So my friend needed somewhere to store medical records in case she goes to hospital, but didn’t really like the standard stainless steel medi-alert bracelets and asked me to make something fancier. A load of lasering and about 7 prototypes later, here’s what I came up with.
The small ones go on keyrings and can store a 20 euro note no problem and a 50 euro if you’re good at folding. The bigger ones are for your handbag or car glovebox and can store maybe 5 times as much.
