I posted this on Joystiq, but I’m putting it here too, because everyone should see it (and also because weird promo items for DS games is definitely TC material): the e-Capcom Gyakuten Kenji teacup.
This delicate item, imprinted with Miles Edgeworth’s face, sells for 1,890 yen from the e-Capcom online store. Capcom is really good at coming up with ridiculous and kind of pointless promotional items.
