This interesting oddities pendant is 1 1/2" across and 1" tall. Three sugar skulls have been electroformed with copper to a real cat rib bone. The metal patina does not completely coat the copper so you can still see some of the metal shining through. I don't coat my pieces so the patina continues to develop to be unique to you and your body chemistry and environment. The bone is from a young stray cat that was hit by a car. Instead of leaving it to be destroyed and ignored, I chose to honor its life by making art from its remains. To save trees and reduce production costs for me (which keeps prices as low as possible for you), I do not include a printed receipt with your purchase unless specifically asked. You can track your package and find your receipt via Paypal. This gorgeous piece will come to you with free shipping, plus a free gift! I ship once a week on Friday mornings. The free shipping is first class with tracking. I may offer Priority if you contact me prior to making your purchase. I do not offer Express shipping. Disclosure: The bones/skulls I use are from various online sellers or from roadkill I collect. Most I process myself. Since I buy from more than one seller, these bones can come from a variety of sources: found bones, bones from taxidermists, trappers & hunters, or from collectors. Bones are *not* the reason people hunt or have animals mounted and/or stuffed, they are a byproduct of these actions. It is up to you as a buyer to decide if this qualifies as an "ethically sourced" product.
