These top-loading page protectors and photo protectors conveniently fit both interlocking D-ring and post bound albums. Featuring high clarity plastic and versatile reinforced holes, these sheets come in packs of 10, and also in a variety of sizes. Each photo protector sheet has individual openings for six 4 in. x 6 in. photos in a 12 in. x 12 in. format, the difference being that one displays the photos vertically and the other displays them horizontally.
