This product is a pack of three Radio Shack Concertape 90-minute cassettes with model number 44-613. The cassettes can record in both stereo and mono and were manufactured in the United States. They are vintage parts and accessories for audio and video equipment. I have dozens of similar cassettes in different time formats. Times include 30, 60, 90, and 120. The cassettes come from a detective with lots of recordings from the 80s. The recordings contain everything from criminal procedures, case reviews, and lectures to family Christmas, sailing trips, and town hall meetings. The selection sold will be random unless directly requested otherwise.
