All of my 3DS things are in one place! The folio is about the size of a CD holder, fits in my backpack well, and has a small case inside that fits in my pocket.The model I received has 21 game card slots and an AR card slot, as well as 2 additional game slots on the inside case for the 3DS. The cards fit quite snugly, yet are easy to take out (unlike in plastic cases where I'm often worried that I'm going to break the game taking it out). I don't really ever use the AR cards, but I also probably won't ever have 29 DS/3DS games to put in the case anyway (as that's how many the other model holds). The AR slot is also large enough for a small notebook, and the stylus holder can obviously be used to hold a pen or pencil as well, so it's more versatile for me.The mesh pouch fits my charger and a cleaning cloth quite well, with some room left. No problems fitting it in.The 3DS case inside attaches to the main folio by two strong velcro strips, soft side on the 3DS case, so it's not going to detach without you pulling on it. The case itself is a millimeter or so too small--the velcro flap doesn't realign perfectly when the 3DS is inside--but it's hardly an issue as again, the velcro is strong and doesn't seem likely to open by accident. As mentioned above, there are also 2 game slots on the outside of the case under the velcro flap, which makes it great for when you know you don't need to bring all 29 games with you. This case is small and fits the 3DS without any extra bulk.Summary:-1 page of DS/3DS card slots (9 per side) + 3 card slots + AR card slot + stylus holder: keeps games and cards secure-mesh pouch fits charger, cleaning cloth, with room for more-small 3DS pull out case has 2 game card slots, attaches to folio and closes by strong velcro
