These combat hands feature 5 individually articulated fingers with 2 joints each and a swivel at the thumb. Rather than relying on ball joints or pop joints, these will require the customer to provide a paperclip to be used as an axle for all of the joints. They also feature a pop hinge joint at the wrist and could easily be adapted for non-kreon customs as they are about Voyager sized. (12mm across the knuckles not including the thumb.)
This set includes enough parts for 2 hands.
