These disc's were part of a 40 pack that I paid alot of money for and I only needed 20 so I'm going to sell the other 20 to recoup some of my money, I didn't realize how expensive these disc are, please look at photos to see features on back of case. Lowball offers will be denied, this item is going to cost me 20 to 25$ in shipping so please remember that when sending an offer, if you want a cheaper price then you will pay exact shipping
