Open jawed Tyrannosaurus ear weights. You should be able to wear this if you have an ear opening of about 15mm (3/4 inch).
These are sold as single earring weights, so you will have to buy 2 to make a pair.
I am offering these at the Shapeways price, meaning that I don't make any profit on them. You are getting them at cost. I am hoping that a few people will buy them in brass, bronze or steel and let me know how they work out. Thanks.
