[Instant Warmth, Reusable]: Move the metal piece to the tip and gently bend it until you hear a click. The liquid will crystallize and generate heat. The neck warmer will then heat up and radiate warmth at an appropriate temperature. You can reuse the neck warmer by repeating this process if it doesn't heat up. *If it doesn't generate heat after pressing the metal piece once, please press it again.
[No Power or Batteries Needed]: This neck warmer generates heat through a chemical reaction of sodium acetate. It liquefies above 80°C and solidifies below 50°C, so it will not exceed 50°C and there's no worry of overheating. The material is also used as a food additive, making it safe and secure! Since it doesn't require power, batteries, or water, it's an eco-friendly and energy-saving product for cold weather. It's perfect for warming your neck, and warming your neck makes your whole body feel warm.
[Sustained Comfortable Warmth]: The neck warmer is encapsulated in high-strength polyurethane, which offers excellent insulation, chemical resistance, and aging resistance, ensuring safe use and preventing leaks. It maintains a temperature of 48°C, providing a comfortable and pleasant warmth at an appropriate heat level! (May vary depending on usage environment, etc.)
