I am looking to buy about 30-40 empty Sega Master System cases for condition upgrades to games I already own. I would also buy CIB games (any games it doesn't matter) specifically for the cases as long as the cases are in good condition. I'm looking for cases in overall good shape with the plastic hang tab at the top still there. They don't have to be dead mint -- minor surface scratches are acceptable. I am looking to buy as many from 1 person as I can. Looking to pay fair prices for both parties. Please notify me via the PM system if you can help me out. Thanks for your time.
