The konjac sponge is 100% naturally made from the Asian Konjac plant. It works to gently exfoliate your skin, shedding away dead skin cells, and giving your skin a smooth, glowy complexion. The sponge cleanses while balancing the skin's pH levels with its natural alkalinity. The sponge is initially hard but softens when soaked in water becoming a very gentle cleanser for the face and body.
