Super Mario Bros. TPU covers for 3DS, by Mori Games. So many accessories lately! These system cases add a tasteful little pixel Mario (and the word “Mario”) to the outside of the case. Each color has a different design, my favorite being the swimming Mario with air bubbles on the blue one.
As usual, I haven’t seen these available anywhere for import yet; in Japan, they cost ¥1,470 ($18.85) each.
