Batgirl is about 2 1/8 inches tall and is sculpted in the stylized Mez-itz vinyl style. I actually have a few of the Hellboy Mez-itz, but that's probably about it. Still, if you've seen Mighty Muggs, Mez-itz, or any other stylized vinyl toy, you know what to expect. The key ring is a fully functional metal key ring, which I'm going to assume you're familiar with.
This is a pretty fun little key chain. It's nothing too special, but it's a great way to sport a miniature articulated Batgirl with you wherever you go. The parts chosen look nice and it seems fully functional so no complaints there. My only complaint is that some of the yellow paint is a bit uneven or not heavy enough to cover the black plastic. Overall, I give it a Good and a 1/2. Batgirl fans will probably want to track it down, but others may want to look elsewhere for something else.
