The U-shaped ring structure is optimized for ergonomics, closely fitting the natural curves of the shoulders and neck, and fitting snugly without hindering movement. Equipped with the latest graphene heating technology, the thin and flexible heating sheet evenly distributes heat throughout the neck. It heats up quickly, providing instant warmth, and the thermal energy penetrates deep into the body, gently warming the core from the inside. This heating method is independent of the outside temperature, relieving stiff shoulders and neck fatigue, and providing both cold protection and relaxation during winter outings, office work, and driving. With wide-area, uniform heating, it keeps your neck warm and comfortable, fully supporting daily fatigue recovery. 【3-Level Temperature Adjustment Function & High-Precision Temperature Control】Easily switch temperatures with one-touch operation! The 3-level temperature modes are optimally designed to suit various scenes and needs. High temperature "Power Heating Mode" approx. 65°C: Ideal for outings in severe winter or rapid heating, instantly dispelling the cold; Medium temperature "Daily Comfort Mode" approx. 55°C: Perfect for daily use such as office work and driving, comfortable even for long periods of wear; Low temperature "Long Energy-Saving Mode" approx. 45°C: Ideal for nighttime relaxation and long outings, enjoying sustained warmth with low power consumption. Unlike conventional products, this product incorporates a highly sensitive temperature sensor. It monitors the temperature of the heating element in real-time and immediately corrects any deviations from the set temperature to maintain stable warmth. Uniform heating without temperature unevenness reduces the burden on the skin and significantly reduces the risk of low-temperature burns. You can freely adjust the temperature according to the degree of fatigue in your neck and shoulders and the ambient temperature, making it a safe and reliable electric neck warmer. - - - - - - - - - - - - - - - - - - ⚠︎Please note that we may change the shipping method from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin!
