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.
It is recommended to select the glossy finish if you would like to write on your passes and remove the written information later.
