Bought these hands from a Taobao seller, to replace my KO TFC Hercules's bad-articulated hands... The seller claim that he designs these hands for the Combiner Wars Devastator but don't want to wast the design so made a few more to sell, and he successfully modded the connector to fit for KO TFC Hercules... Need to trim and perhaps sand the surfaces smooth... also need to paint them metallic purple... Hope my paint still has enough... Costs about SGD 9.25...
