This case includes 10 holders for 3DS card, in which, however, also normal DS card reinpassen +12 holders exclusively for normal DS card + 2 holders exclusively for SD cards. The case is therefore super handy if you go to any events or friends and want to take this all his games. For me personally, one holder for memory cards would have been enough and the case looks a bit modest when you have fed it with the DS cards. That's just the downside of the transparent design and the "hama" logo is also transparent, although that does not look at the picture so. However, I have the problem resolved by I the outsides simply decorated with stickers :)
