It's a centimeter long and made of plastic.
Allow me to expain- this roboclaw came with the Hasbro Anakin Lightsaber Action(tm) action figure. Anakin comes with very own lightsaber, evil looking cloak, and two types of hand: a gloved hand, and a hand with the gloved burned and all the robo-goodness exposed. Also, when you squeeze his plastic legs together, his lightsaber swishes up and down in his roboclaw hand. Anyone with this same figurine knows what I'm talking about. I'll post pictures of him and the roboclaw as soon I can borrow a friend's digital camera.
I ♥th my roboclaw!
