This is a clear file. I think I got it at an event or something. The design is from the PC8801 game "Lamia 1999," released in 1987. The manufacturer is Hudson. The material is thin plastic. It's unused and was in a plastic bag, so it seems to have almost no scratches. When held up to the light, there are a few slight dents. I plan to sandwich it in cardboard and ship it via Yu-Packet Post in a Kakugo 2 envelope. Since it's an old item, please refrain from claims or returns.
