Looking for some help here. I bought a couple of phone cases hoping to engrave on them. But I know there are specific materials you should not engrave on for health or saftey reasons.
These cases have wood veneers on the back, which should be fine, but they are only .06mm thick. The plastic underneath is TPU (Thermoplastic polyurethane). So my fear is that while engraving it goes to far and starts into that, or that it is some weird mix across the board. Googling TPU gave me not a lot of results in this department. Anyone with any experience? Or know of a better phone case to be buying and engraving? Below is a link to the specific one.
