This BCW Z-Folio LX has 4-pocket pages sized to hold 160 toploaders. It works great for sports cards, trading cards, and gaming cards that have been inserted in 3×4, standard-thickness toploaders. The folio has a leatherette cover with stitched edges. A durable zipper ensures that cards will not fall out of your album. Unlike a binder with removable pages, our double-sided, archival-safe, polypropylene pages are welded into the album.
