Thank you for looking! (o^^o) The surface that touches the skin is made of a soft, fluffy material like felt. The back is entirely waterproof. It's a slightly larger size, making it easy to use as a panty liner. (Fully waterproof, for heavy flow days, for light flow days, for vaginal discharge, for urine leaks, cloth liner, period panties, warming, for nighttime, black, trial)
