Cosmic GLOW Coasters
Swirling, colourful coasters that GLOW in the dark!
Watch it GLOW!
Beautiful by day, glowing by night!
Let your cosmic GLOW coaster absorb light energy from the sun, a lamp, or an ultra violet bulb. The higher the light intensity, the more energy the phosphorescent pigment can absorb and the brighter it will glow when it releases the light energy in the dark! Each one comes with a helpful card (see photos).

Each one is individually made by hand so has a completely unique pattern.

Meet the snake whose skin is in your pendant, and learn about "Ecdysis", the process of skin-shedding!
Simply scan the QR code on the card that comes with your pendant and watch the video to learn about our beautiful pet corn snake and how, why and when she sheds her skin.
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. It doesn't cause them any distress and the shed "skin" is simply discarded. Availability of these pendants (and the key ring version, SnaKey Rings) 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
Available in six colours (see photos), Green, Gold, Blue, Purple, Red and Copper and each comes in a velvet pouch (colour coordinated, subject to availability).

Bespoke: Send your own snake shed! (adds £2 to price)
If you have your own snake and would like to send its shed skin to be captured in a SnaKey Ring, just select the "Bespoke" option below. Shortly after purchase you'll receive an email with instructions for safely sending your shed skin with a short form to complete (please check your spam folder, you'll need to print the attachment and send your shed in it). You'll be able to indicate your colour choice for each SnaKey Ring on the form and if you'd like a colour not listed here you can let us know on the form and we'll do our best to find a match. Your skin will be returned to you as a beautiful SnaKey Ring!
Please note that you'll need to post (at your own cost) a flat section of shed skin measuring min. 10cm x 5cm. Providing the skin is flat, in good condition and of approximately the given size this should be possible with any age or species of snake. If you can't provide a piece that size let us know the largest you can send and we'll see if it might work. If the shed you send can't be used, we will of course refund your SnaKey Ring payment. Sparking STEM can take no responsibility for your posted skins and recommend obtaining proof of postage.
Your bespoke SnaKey Ring takes a while to make as there are several steps involved in preparing and capturing the skin, please allow an estimated ten days between the day we receive your shed skin and dispatch of your SnaKey Ring to you.
