Bootleg (fake) vs original (authentic)
GSC has posted yet another bootleg comparison of some Nendoroid. The featured Nendoroid are: Nendoroid Kaname Madoka, Nendoroid Hatsune Miku: Absolute HMO Edition, and Nendoroid Dead Master, versus their bootleg counterparts. Out of those three, I personally have difficulties to distinquish between Nendoroid Kaname Madoka and her bootleg version. Well, gotta be careful to purchase Nendoroid from untrusted stores. XD
Anyway, feel free to visit the source pages for more pics and info (in Japanese XD) about the comparison. ^^

Some will have to really careful then. Then again it wouldn’t make much of a difference for those who don’t care.
Hooray! A whole new batch of bootleg Nendos to have to watch out for. Thanks bootleggers! -_-
Personally I already own these and don’t have to worry about buying a bootleg, but I have bought one before and it sucks…. not a good feeling o_o
