Our newest polypro outer brings Diskeeper protection to 10" records. Made from our exclusive hybrid 2.5mil polypro/polyester film, each sleeve is die-cut to perfectly fit 10" record jackets both old and new. They do not cloud like polyethylene, nor do they split like expensive Mylar sleeves, and they are manufactured to the absolute highest standards of quality. These are, without question, the best 10" outers for sale anywhere. Measurements: 10 3/4" x 10 3/4".
