This is the Wonderswan game "KISS yori... ~Seaside Serenade~" (cartridge only). It includes the game cartridge and the cartridge case. I have confirmed that it starts up. There is discoloration due to aging, as well as scratches, scuffs, and other wear and tear. Please consider this a used item that has been stored by a private individual. Immediate purchase is welcome. I will ship within 24 hours. Thank you for looking.
