For sale is the entire Objective Communication 20 casette course. It is in mint condition. I have only listened to two of the casettes. The rest have never even been taken out of the case. I've had it for a long while and just never made use of it. The course is in two large white clamshell cases, both of which are in nearly mint shape.
Best offer takes it. Buyer pays shipping.
