These binders feature a 720 card carrying capacity, with side loading pockets that both prevent theft and keep your cards from slipping out of place. Each of the pages are cushioned to give your cards an extra level of protection. Monster Protectors binders also feature a custom binding that expands as you put more cards into it, so the cover always stays flush against the pages, never exposing your cards to harm. All of the pages are also stitched in rather than being glued in so the binders are incredibly durable and last for years.
