Our 30mil RockStar Flush laminate passes are all able to take writing with a Sharpie marker, or a 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! This will allow you to use a common or more generic pass from one event to the next, without having to wait until the last minute to collect a complete registration list. It is also nice in the event a guest can no longer attend and someone else is there to take their place.
