We have all used a plastic jewel case or a plastic cd sleeve and know how they crack and are usually made of a material that can't be recycled. Our RESLEEVE is made of a rigid 16pt recycled bending chip board and has a round die-cut hole in the center to view the front of the disk. The back is solid, embossed with the message "RESLEEVE 100% Recycled". RESLEEVE is made from 100% Recycled Fibers (56% Post Consumer Recycled / 44% Post Industrial Recycled). Great for storing, protecting or used as a mailing envelope for your CDs. Perfect for the Band or The Board Room.
