This copy of Pokemon has a new battery installed, and has been cleaned inside and out. I created a custom case by cutting out part of the inside of a Nintendo DS aftermarket case, see pictures. This process leaves scratches and small pieces of black plastic inside, it isn't the prettiest but creates a good hold for safe storage of the game.  The case insert is printed on photo paper with archival inks. Cartridge label has some wear, please see pictures, as what you see is what you get! Tested and works fine. If you have any questions, please ask!
