I love this Tibetan Style Pendant that's on sale now at Panda Hall. It's a flat round gear charm, antique silver in color, cool for steampunk jewelry making. It's safe; free of lead and nickel. It is 38mm in diameter.
One hundred of these will cost me only $33? I haven't tried buying from the Panda Hall site before but it looks like a great place to buy neat trinkets and make your own jewelry for sale in bulk.
