About this Product
This model has been tested in WSF by EchoTransformer
These hands are upsized and modified versions of my Kreon Combiner Combat Fists designed to fit the Boosticus upgrade set from EchoTransformer. According to EchoTF, the hands will also fit the TFC Uranos combiner.
I'm testing these out now to see if they will also work on the new Combiner Wars figures from Hasbro.
