Warm pad patch uses the oxidation reaction of iron powder and oxygen in the air to generate heat. The material needs to be made of air-isolated gelatin material and microporous air-permeable non-woven material. After tearing off the air-impermeable material, heat can be generated. The microporous air-permeable technology allows the iron powder to slowly contact the air, so the temperature can be maintained for a period of time. After unwrapping the outer packaging paper, it can generally maintain its own temperature between 51 and 60 degrees, and continue to generate heat for 12 hours.
Step1. Tear open the outermost plastic vacuum packaging of the heating pad patch.
Step2. Peel off the sticky sticker on the warm pad.
Step3. Put the warm pad on the outside of the underwear, remember not to touch the skin directly.
Step4. After use, gently tear off the warmer stick from the clothes.
