The sad part is that you could probably find them in Nakano Broadway for about 600 yen, maybe a bit more. ...of course, you have to go to Japan to do that. XD I got the whole FF6 keychain set for like 15 bucks there. I wish they'd had some CT stuff... Maybe I didn't dig deep enough.
It's also a good idea to check the Yahoo Japan Auctions--sometimes they sell stuff way cheaper than their American counterparts. (Reminds self to go check around for the Tenshi Souzou manga)
