DS Duo Game Case

DS, Lite, Duo Game Cases, Mario Kart, Metroid Prime: Hunters, Yoshi and The Legend of Zelda: Phantom Hourglass.
Bought these (DS Duo Game Cases, Mario Kart, Metroid Prime: Hunters, Yoshi and The Legend of Zelda: Phantom Hourglass.) a while back, to sort of sort and keep my carts in a neater pile. They can only contain 6 game carts each and an extra stylus (>o_O) Do people keep losing them?

So I can now store 24… That isn’t enough, no? Seeing the amount of games, I have now… Not even enough to stores those not lent to a friend~!

Maybe I should buy the pink peach duo game case too..
