Those are awesome. I was going to ask about the scratch resistance, but I think you covered that. Great idea for short runs to decorate things like the hard hats. Thanks for sharing.
My friend Spencer has actually had one on his phone case for 3 months and it still looks amazing. The only damage to it is where is has been "picking" it off intentionally.
These are really cool, but not waterproof right? Do you know of any printing method that provides UV stable print with waterproofing? I am trying to find a good way to print plant tags and they would get wet with watering as they are meant to stay with the plant.
