Quote: "I’m back with a quick review for you of some cases basically, they’re cases for your Nintendo DS cartridges. They don’t have a fancy name just Protective Game Card Cartridge Cases for NDSi/NDS/NDS Lite and it’s a five pack of them that I got from Deal Extreme for only $4.68. Yes it’s a very basic product, but it’s one that’s needed especially if you’ve got many games and kids as I do. We’ve got the DSi XL and the DS Lite and plenty of games to go with them that we just kept in a bag really which wasn’t the most protective way of doing things. I thought it was time to get something better, so I grabbed these and they work and they’re very inexpensive… "
