I was working on one of these beasties for a 3DS XL and it came out a little... small. As you can see, it just snugly fits a normal 3ds or a normal ds. It could also fit other game consoles of that size with about a cm of the top peeking out.
The case is polar fleece sewn over top of memory foam with a hand stitched zorua motif. The front having the face markings with the back sporting the back of the hair spike and the back of the neck fluff.
The top has no latch so the ds might slide out if held upside down, but the case is plush enough to protect from scratches and bumps within bags and whatnot.

As it is FAR too small for its' original owner, I am putting this one up for auction.

Starting at $15 even (shipping free if in North America at all and pretty minimal anywhere else in the world) this hand made one of a kind case of plush cuddliness will be sent out to whoever bids the highest by next Friday (April 12th).
I'm not overly fussy and can easily be bribed or persuaded into deals that peak my interest. You guys know me. :P
