Here's what we're delivering: This item minimizes differences in appearance due to the pattern. The item will be labeled as "Handkerchief" for shipping. Please feel free to purchase with confidence. This is a set of three fully waterproof items made with carefully selected Japanese materials. Size: Approximately 22cm (length) x 17cm (width) (slight variations may occur) Layer 1: Unbleached double-sided flannel (skin-facing) Unbleached double-sided flannel is a gentler fabric than standard products. There may be small black specks on the surface; these are cotton seed husks and are proof of being unbleached. They are harmless to the body and will come out in the wash. This item uses the same fabric as a certain cloth menstrual pad manufacturer. Layer 2: Breathable waterproof fabric (repels moisture but allows humidity to escape) Layer 3: Double gauze (underwear-facing) This waterproof type can be used for a wide range of purposes, including sweat, minor leaks, vaginal discharge, and menstruation (due to individual differences, we cannot guarantee against leaks). It can be used comfortably for warming activities, fertility treatments, during sensitive pregnancies, and by those experiencing menopause. #HIKARIE's Room
