This is a "Baby Vise". According to the listing: "This is a great item to have around the house or shop. The body is made from a high grade cast iron. The bottom of the vice is a clamp that will attach to any flat surface. The jaws have been polished and they open up to 1". Small enough to fit in your back pocket!"
I thought this would be a great idea for giving Catherine haircuts, clipping Elisabeth's nails, changing diapers, etc.
My main concern is that the 1 inch version wouldn't be quite big enough for them, and I'd probably need 3 or 4 strategically placed Baby Vises to secure all the arms and legs. Let's see, $3.99 each, plus $4.75 shipping....
Hey, it's not like I'm making a Bonsai Baby out of them or anything.
