All of our passes can safely be written on with a Sharpie or dry-erase marker.
While a dry-erase marker sounds less permanent and maybe ideal, we actually would recommend writing on the passes with a Sharpie or permanent marker, as written material won't rub off while being worn.
To erase names, if desired, just use 70% Isopropyl rubbing alcohol on a paper towel or rag and wipe away the name!
