NEED-old GBA cartridge case

Hi everyone! I'm in the middle of a costuming project and I need to find one of these old GBA cartridge cases: Scroll down to the last in the GBA accessories, # 505-03036

It looks like a mini GBA game, but was designed to hold a cartridge. I just need one, but if you want to get rid of more than one I'm sure I can find other people to take them. It's something that when painted silver, goes in the pocket of a Viper flightsuit. PM me if you have one. I'll pay a buck or 2.
