Box of 500 mylar adhesive-back PVC cards. These CR79 cards are 10 mil in thickness with a 14 mil mylar back. They are designed to fit within the inside edge of a proximity card. Since proximity cards are usually too thick for most card printers, you can instead print personalized card info on these thin adhesive-back cards, then remove the backing and affix them to the thicker proximity cards.
