Not sure if it was me, but I'd recommend
4Gamers
It's nice kit, well made generally, though the new DS lite case isn't so hot, but they were good about me returning it and getting a original DS one (gives you space for games and bits), it's also the same cases both my nieces have and they have yet to break them
Though it doesn't look like they just do a stylus pack :/ So ignore that unless you are after a case and well and go with play asia
