It is acid free and contains no wood fibres. All pages are pre-printed (illustrated). The pages are purposely printed in black and white, to allow you to identify at first glance, which stamps are still needed. These pages are with mounts. The SF mounts are affixed to each individual illustration in the exact size of the stamp. SF mounts are manufactured of clear, safe polystyrene film. The clamp-type seal at the bottom of the pocket securely holds the stamp in place.
