Well if you really wondered.... They had given some out a bit ago... Real crystals on a Tama-Go...? I highly doubt it as its a kid's toy.
Looking at it, people can purchase crystal like stickers and put them onto a Tama-Go. (Jolee's is a famous sticker company that makes stickers simmilar to Swarvarski Crystals) You can use these instead and get the same effect, more even and better looking.
The ones that were given out, have some larger stickers on them and these have a pointed angle on top. Otherwise, the stickers look like adverage crystal stickers.
Ugh. Pretty, but not worth the cost, even for a collector.
