This is a set of three TDK audio cassettes: 'MA-R90', 'SR-X50', and 'AD46'. Unopened and unused, stored indoors. However, due to their age, the packaging has some wear, scratches, and dirt. There is also the possibility of age-related deterioration. Since they are unused, the functionality has not been tested. Please understand that these are essentially new, old stock items, and only purchase if you agree with this. Please check the photos for the condition.
