Brand new and high quality paper and poly lined record inner sleeves for perfect protection of your precious records. High quality plain paper and anti-static high-density polyethylene lining. The silky outside layer of paper gives the sleeve stiffness and shape which makes it easier to open and insert a record. The poly lined inner surface lets the record slide with minimal friction and static. The clear PO film protects it from dust and dirt entering the center circle and allows you to read the album label.
