Each pendant is handmade and contains a unique section of real, naturally-shed skin from our pet corn snake (her name is Nagini). Corn snakes, like all snakes, naturally shed their skin several times a year (the process is called "Ecdysis") so that they can get rid of the old skin to reveal a beautiful new one underneath.

Availability of our snake-shed range is limited by the rate our snake sheds her skin, so please be patient if stocks are low and let us know if you'd like us to let you know when your choice of colour is in stock, or if you'd like a colour that you don't currently see here.
Handmade and unique
Please note that as each one is handmade individually, there may be subtle variations from the photos. Each background is hand painted with metallic paint and the shed is captured in resin, which is carefully applied to each one to bring out the shimmer of the background with a robust finish. Each one is unique, but made with equal care and attention to detail.
Colours
