A set of audio cassette tapes: one with a metal position and two with normal positions. I purchased these new and stored them unopened at home. Although they are unopened, they are several decades old, so I cannot guarantee they will actually work. Please understand this before purchasing. Due to the above reasons, returns are not accepted. Thank you for your understanding. 《Metal Cassette Tape》 Product Name: Audio Cassette Tape Position: Metal Position Recording Time: 74 minutes round trip / 37 minutes per side Country of Origin: Japan Manufacturer: Sony Corporation SONY 《Normal Cassette Tape》 Product Name: Audio Cassette Tape Position: Normal Position Recording Time: 90 minutes round trip / 45 minutes per side Country of Origin: China Manufacturer: Konica Corporation Konica
