50 pack of superior-quality outer record sleeves made from completely transparent, high-density polypropylene. Uniquely designed for durability, they are the perfect fit for 12" vinyl records. Safeguard and enhance your albums — Made from archival quality polypropylene, our outer record sleeves actively protect your jackets from moisture, dust, discoloration and general wear. Crystal-clear and acid-free to enhance the artwork of both old and new LPs. Perfect fit for 12" vinyl — Precisely cut to 12.75" x 12.75” and ideal for single, double and most gatefold 12" LPs. At 3 mil thick, our outer record sleeves provide the perfect balance between protection without adding unnecessary bulk. Uniquely designed for extreme durability — Our outer record sleeves last longer for one reason: they have a single bottom seam/join (others have two side seams). This prevents side-splitting while inserting or removing your albums, so you only sleeve your records once.
