3DS Card Case 18 and its box slips. Though I mentioned that Nintendo started offering this to Club Nintendo members (in exchange for 250 Coins) this morning, it’s so neat I’m dedicating a post to the accessory.

It’s already rad that this thing is almost the same size as a standard DS/3DS case (just a bit thicker) and holds up to 18 cartridges, but it also comes with four different sheets — including one with that awesome Nintendo Conference 2011 vector art — that you can slip in and use as a cover.

They have inside art, too, which shows artwork or icons in spaces you haven’t filled with games. For those wondering if you can use these with standard 3DS cases, I tested it and they fit in fine, but you can’t see the inside art through the eco-friendly holes in the plastic.
