This item is an accessory or set of accessories for Gundam models. It requires both cement and painting to complete or use.
Here's a super-detailed set of unassembled hands, molded in white and light gray, in the poses shown below (the photo shows the hands cleaned up and painted; you'll need to do that yourself). Intended for use with Bandai's 1/100-scale MG Gundam Exia kits, linked below.
