Our Diskeeper anti-static inner sleeves are superior in all respects to traditional paper inners. The strong, smooth 2.0 mil HDPE doesn't tear easily or leave dust or static on your valuable records, and the entire sleeve is translucent, leaving no need for a center hole through which contaminants may enter from outside. If you have never tried full HDPE anti-static record sleeves, you will be amazed at the improvement over paper sleeves. Never brush paper dust off your records again! Measurements: 12.0625"x12.0625".
