Sponge roll is made of hydrophilic polymer PVA (polyvinyl alcohol). Because of the micro-pores of the hydrophilic substrate, Sponge roll has good water absorption, water-retention capacity. Technical specification: * Cleaning surface without vapor hole and strong elasticity * Weight of drinking can extend ***0 times of its own weight * Normal life cycle in gear is **6 months Technical parameter: * The degree is no more than *0 degree when using * Conserving in water when no using and do not be pressed avoiding distortion
