⭐️ Brand New ⭐️ Warmer Neck Ring, Hand Warmer, Cold Protection, Energy-Saving Measures, with Scarf Warmer Neck Ring With Scarf I received this as a prize at a year-end party. It's an eco-friendly hand warmer that can be used repeatedly without batteries. It works on the principle of crystallization caused by the impact of the liquid inside, and it heats up immediately when you press the metal button inside. The temperature rises to 50°C in about 10 seconds. It comes with a scarf-style cover to stylishly warm your neck.
