*Multiple Sizes* Gameboy Cartridge Holder (Up to 10)

Gameboy Cartridge Holders that go all the way up to 10. If people want more sizes just do a comment or something.
They fit normal Gameboy cartridges pretty well, for me I can turn the cartridges upside-down and they wont fall out, but I'm not sure about GBA cartridges, since I don't have any of them
