Nintendo's never sent me a Club Nintendo bonus for review before, and I thought it was kind of odd when one arrived. But I don't think there's ever been a Club Nintendo bonus this nice. The 3DS Game Card Case is both beautiful and genuinely useful, holding 18 DS or 3DS games in a case the size of a single DS game box. That's a rarity among DS game cases.

The transparent case comes with four reversible covers, for a surprisingly versatile look. I grabbed some random DS and 3DS cartridges from my desk, stored them in the case, and took some pictures so you can see for yourself.
