(1) Twist the stick's dial to extend the product by about 5-10mm. (2) Apply evenly to the dry, clean spaces between the toes, the base of the toes, and the entire soles of the feet. (3) After use, close the cap tightly and store away from direct sunlight and high temperatures and humidity. ※ If the cap is difficult to open, twist it slightly before lifting it straight up. ※ If you sweat, wiping it off before use will be more effective. I opened it, but I didn't use it.
