Not gonna lie, this one looks like The Eye Of Sauron. Perfect for those who want to rule Middle Earth with the iron fist of the Ork.
Taxidermy eyes are great from crafting, jewelry making or just gluing eyes all over your friends belonging to tricking them into believing their water bottle is a Lovecraftian elder god. Of course, they can also be used in your taxidermy adventures as well. Each is made from glass and has a concave backing.
