I bought this at the Mingei Museum gift shop, when I was there last week. (Gosh, I love that shop! I've bought tons of stuff from there.) It's large lock, made of metal and (duh) shaped like a hand. I have lots of hand imagery around my house. I know many people must use their mouths, or feet to hold a pen or brush to create art, and I'm very thankful for my strong hands.
