Heads up Polymer Clay.

It may be just me but just notice polymer clay is made up with PVC. If you engrave your own pens do not engrave anything with PVC in it. The chlorine out gases during the engrave and corrodes everything in the laser. Most warranties on the laser do not cover engraver on PVC.

Did not know that. Good to see my day ending learning something new. It would seem that if you wanted to engrave it then adding some band of wood, metal or other material you could engrave would be in order.
