Thank you for viewing! (o^^o) The skin-facing side is made of 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. *Please note that the button position is off-center or slanted. Please check the last image. The item in the photo is the one in the worst condition. There are no issues with use, but we apologize for not selling it at the regular price, so it's on sale. (Fully waterproof, for heavy days, for light days, for spotting, for bladder leaks, cloth liner, period panties, warming, for night, black, trial)
