Nature offers some of the greatest color combinations. The colors of the Green Mamba really pop so it seemed like a natural choice. One of the fastest and most venomous snakes in the world has no place near your fingers but our new ring certainly does. It's got a great pattern and bright green color. Our ring has a trick the snake doesn't, our ring glows in the dark! Expose it to UV light and turn off the lights and you'll see. In the second picture you'll see it glowing. Every picture on this page is the same ring. The glow time varies with the light used to charge it but it will glow brightly for a few minutes even with minimal charge. Get one while they're on sale!
