“Honobono Ace”a medical thermotherapy product

“Honobono Ace” is a medical thermotherapy product (hot compress) that can be applied directly to the skin to provide simple thermotherapy.
Unlike warm types that contain ingredients such as cayenne pepper that may irritate the skin, our hot compress warms up to around 40C when applied directly to the affected area to provide a warming effect.
Warmth at a temperature of around 40 °C, close to the temperature of a bath, continues for 5 hours to enable stable thermotherapy of the affected area and relieve pain and stiffness by improving the blood circulation, making this an especially effective method of treating chronic pain in the shoulders and lower back.
