Can I engrave these with the Aura?
Most likely…if they don’t contain any stuff that would be dangerous. The best advice I can give is to test on one of them. The settings will be completely your call, since it’s doubtful anyone else has tried them. If they are 100% rubber, they might be pretty smelly…but really…check out what they’re made of and if you do anything, post your results in here.
This came up once before, and I remember giving the same advice about being sure that’s 100% rubber.
Most pencil erasers are actually not pure rubber, they usually have abrasives in them which are not likely to be laserable. You can probably get a pretty good result though, just I wouldn’t try to go too deep.
According to Amazon, they are made of Thermoplastic Elastomer (TPE). I don’t know if there is something else in them, but that’s all it says for the material.
