The Game Card Case can accommodate 24 3DS games. There is a holder for an SD card here. The only downside: It can be a bit difficult to open at the beginning, which is, however, the more you use it. Otherwise, it's great for the transport of several games and takes naürlich significantly less space than if one drags all original case, which is handy when traveling, especially because all the games in one place and are nothing goes lost.
