The brand on the box and tape/spool may not be the actual material in the box. The Ampex case looks to have a spool that has Audiotape Brand so I can't speak to what type of tape is on that reel. Nor can I speak to the quality of these tapes because I cannot test them at the moment. These items are sold as is. The cases and spools are in very good shape. No writing on the boxes.
