Thank you for viewing! (o^^o) The surface that touches the skin is a soft, fluffy material like felt. The back is entirely waterproof. It's a slightly larger, easy-to-use size compared to regular sanitary napkins sold for everyday use. (Fully waterproof, for heavy flow days, for light flow days, for panty liners, for urine leaks, cloth liners, period panties, for warming, for night use, black, trial)
