Animal Teeth Glass Vial Necklace £4.99 £4.99 Add To Basket 1 in stock. You're looking at a test tube style glass vial necklace, filled with tiny mouse teeth. I've found the teeth in owl pellets which were carefully dissected. The teeth are cleaned and whitened. The silver toned necklace is 17" long, the vial with cap is 3cm in length. Note that the vials and the cap are sealed.
