The Archival Methods CD/DVD Sleeves are clear, inert polypropylene sleeves for the storage CDs and DVDs. They are significantly less bulky then jewel cases. The sleeves hold two discs with an interior non-woven divider. The black non-woven, static-resistant fabric is a clean room material that will not shed or form lint. Dirt will fall through the fabric and become trapped away from the disc where they cannot scratch the play surface.
