Here's what we're delivering: This item minimizes differences in appearance due to the pattern. The item will be shipped with the description "Handkerchief" for your peace of mind. This is a set of three fully waterproof items made with carefully selected Japanese materials. Size: Approximately 22cm (length) x 17cm (width) Layer 1: Flannel fabric (skin-facing) Unbleached on both sides (only in photos 7 and 8) - a set to try patterned flannel fabric. Unbleached double-sided flannel fabric is gentler than standard products. There may be small black specks on the surface, which are cotton seed husks and a sign of being unbleached. They are harmless to the body and will come off with washing. The same fabric is used as a well-known cloth napkin manufacturer. Layer 2: Breathable waterproof fabric (prevents water from passing through, while releasing humidity) Layer 3: Double gauze (underwear-facing) Fully waterproof, it 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). Comfortable for those seeking warmth, fertility treatments, during sensitive pregnancies, and for those experiencing menopause. #HIKARIE's Room
