These were an interesting idea around 3 or 4 years ago – a slice of laser engraved veneer which you stick directly onto your iphone. They looked great, but functionally they weren’t so good.
Problem was they didn’t protect the most vulnerable parts of your phone – the edges – as they weren’t actually a case. Much better idea would have been to adapt an existing case (e.g. a sublimation case) and attach the veneer to that.
Still, the idea was nice and some of the designs were good!
