An alarm sounds every 20 seconds. Washing for too long can remove the necessary sebum from the skin, so it's designed to prevent that♪ By using this alarm as a guide, I was able to use it with peace of mind, preventing skin problems caused by over-washing◎ Waterproof construction, so it's okay if it gets wet.
