Thank you for viewing! (o^^o) The skin-facing side is a soft, fluffy material like felt. The back side uses waterproof fabric throughout. It's a slightly larger size, making it easy to use as a panty liner. *Some products have increased in price due to rising purchase costs. (Fully waterproof, for heavy flow days, for light flow days, panty liner, for urinary leakage, cloth liner, period panties, warming, for night use, black, trial)
