This guys aren't the cutest keychains i've ever seen, but i like the concept! they're a novelty and novelties go far with me...The Hotohori and Nuriko are pretty cool, the Tasuki normal is ugly in my opinion, although i do like the Tasuki SD alot.
BTW, there are five characters in the whole set for these guys. I neglected buying Miaka and Tamahome (not enough O-K-A-N-E). I got these for $10 a pair, but i don't remember the name of the store, sorry.
