These 12” Anti-static Vinyl Record Sleeves come in a pack of 40 sets designed to protect your valuable vinyl collection. Made from PVC-free, anti-fungal, and dust-resistant materials, they guard against static, scratches, and common damage found in standard sleeves. Constructed with three layers—two 4 mil HDPE plastic layers and a middle alkaline, acid-free 70g paper layer—these sleeves offer added durability and rigidity. Measuring 305 x 305mm with a thickness of 0.04mm, they provide superior archival protection and long-lasting preservation for your records.
