Drilltapes Audio Reinforcement For Modern Math Home School 80 Cassette Tapes

What you are buying is a very unique and vintage math learning set. You get the large Drilltapes box the includes eight different compartments of cassette tapes. There are eight color coded sections of ten tapes each. I do not have any other instructions other than just the tapes in the box. The tapes all appear to be in nice overall condition but they have not been tested. I will do my best to answer any questions you may have about these.
