Sam White of Nano-Ice created this handmade Nano Ice Cooling Necklace for his wife while living in India. She suffered from India's unbearable hot weather and he wanted to help her find relief and he ended up creating a wearable cooling technology that fits into a beautifully designed necklace that anyone, both men and women, can comfortably wear. Here at Nano-Ice, our goal is to help you Beat the Heat in Style and help those who really suffer from the heat. The cooling technology inside lasts for around 2 hours after you take it out of the freezer. Today, they are hand crafted outside of Boston and we are proud that we are improving the livelihoods of people who are in our community. Please be aware that the Nano Ice Cooling Necklace is much bigger and heavier than a typical necklace as it contains 1.5 inch balls with liquid inside. We hope you find the Nano Ice Cooling Necklace helpful. I embedded my cooling technology inside a beautiful necklace. This necklace does not need to be wet, as your neck is actively cooled from the frozen spheres inside after you take it out of the freezer. INTRODUCING OUR NEWEST COLOR! THIS fun Light PURPLE WILL BRIGHTEN YOUR WARDROBE. FABRIC: 100% POLYESTER, Bathing suite fabric. This Body Cooling Necklace is a must-have accessory for people who struggle with Heat Issues.
