Could you please post a warning about engraving Moleskines. We found out through one of the other guys who also engraves the books (Joe Mansfield) that the covers contain PVC. We have gotten a good bit of internet coverage on our site, and I know (having had several emails from people) that we have inspired others to do the same, so we want to issue this warning:
WARNING!!!!: Do NOT engrave sketchbooks (in our case Moleskines) or any other materials without the proper PUREX PVC filtration system. Burning PVC creates several carcinogenic gases along with dioxins and also produces hydrochloric gas. Burning this without the proper filtration device IS HARMFUL to your health, and the hydrochloric gas WILL corrode your machine.
Laser tattoos are still ok (just kidding).
