The album sheets are made of acid-free card (170g/m 2). SF protective pockets made of crystal-clear, anti-glare polystyrene film free of chemical softeners are affixed in the sizes of the printed stamp form to the album card. The protective pockets keep the postage stamps precisely in place and prevent them from sticking. They also provide optimum protection against dust and damage.
