Abstract
A single sheet of non-woven material is provided with sufficient strength and durability to store one or more compact discs without the necessity of laminating or otherwise interconnecting the non-woven sheet to a backing sheet or other materials for strength. The single sheet of non-woven material is positioned opposite the playing surfaces of the compact disc to provide a non-scratching, protective surface and to reduce the costs associated with manufacturing the sleeves used to store the CDs.
