This brush is made of selected natural bristles that have been sterilized at high temperature. It is strong and flexible, and softens when soaked in hot water. Perfect for wet use in the shower, or as a dry body brush for exfoliation or dry brushing. The bath sponge net is soft enough to be used on the most delicate skin, and will never scratch your skin. Gently rub to create abundant lather, letting you enjoy the comfort of the shower.
