Japan is crazy for DS-themed keychains
Seriously, they have got to be with so much keychain crap thrown around in that territory. But we really can't comment, as we do not live there and have never visited. Still though, they aren't the toy capital of the world because they're always peddling junk wares, as exhibited by the very tasteful and highly-desirable keychains pictured above.
We have no idea if those game cases actually open up, or if the DS hinges are functional, but we want them nonetheless. What about you?
