The Perfect CD Envelope is manufactured with special non-woven polyester material that will not shed or form lint. Its design is superior to paper, vinyl, or felt envelopes, which can scratch or damage your disc. The Perfect CD Envelope provides both safety and protection—without obstructing your view of the disk inside. This is a lightweight, cost-effective alternative to the standard jewel case. The perfect CD Envolope can be purchased in a pack of 100.
