I bought this with my Black DS Lite mainly for the case, which is reasonably solid, with 4gamers written on the top surface in black. Inside the case are 4 elastic straps designed to hold your DS or accessories in place within the case and a "Made in China" tag in white, which you'll probably want to cut out. The cartridge cases and styli don't fit into a pocket or other sealed area within the case, so be warned that they might fall out if you don't open it carefully. The case isn't really big enough to store anything except the DS itself.
The emergency battery charger is a good idea and the cartridge cases can hold 4 games - allowing you to carry 5 DS games at any one time. The emergency charger will not fit into the case though.
The major thing missing from this pack is a cleaning cloth though, since the DS Lite attracts fingerprints and dust to the screen area and casing like nothing else.
