All Clean Skin Club Clean Towels are made of viscose. Our Bamboo Clean Towels are made of viscose with bamboo as the material source. Viscose is a partially man-made cellulose fiber derived from the pulp of various trees and plants. To make the Bamboo Clean Towels, bamboo is harvested from managed plantations then broken down into chips that are then washed and cleaned. The bamboo chips are dissolved, turning them into viscose, and then sent through a spinneret which produces the soft, cellulose fibers. This fiber is then stretched and pressed, turning them into Clean Towels. The finished product is an ultra-soft and absorbent facial towel that is tear + shed resistant, and gentle on even the most sensitive skin types.
