Natural Konjac Konnyaku Body Sponge: This Eco-friendly sponge is made from a fiberous vegetable common to Asia. It is soft and suitable for sensitive skin. Directions: Unlike most sea sponges which are naturally soft to the touch, this sponge must first be soaked in warm water for 2-3 minutes to soften its fibres, then use as desired. After use, rinse it thoroughly and hang it to dry. It fits nicely in your palm. I love that it comes from a vegetable and it is totally sustainable and Earth friendly. Compost it after 3 years.
