DS Game Software/Cartridge Case It's made of a material that feels like metal, not plastic. (Game Boy Advance cartridges are also compatible, apparently) I received this as a gift and have kept it unopened. There are some minor scratches on the packaging, but they are not very noticeable. Shipping via Post Mini. Instant purchase is okay (If paying at a convenience store, please let me know your expected payment date). No price reduction.
