Driver's License Laminating Pouches are 2 3/8" x 3 5/8" and come in 5, 7 or 10 mil thickness. The thicker the laminating pouch the more rigid the result. A 5 mil driver's license pouch will be fairly flexible, a 7 mil driver's license pouch will be more rigid with some flexibility and a 10 mil pouch will be quite rigid.
