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," so you can 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) Layer 1: Flannel (skin-facing side) This set allows you to try unbleached double-sided flannel (photos 3 and 4 only) with a pattern and color (light blue). Unbleached double-sided flannel is a gentler fabric than standard products. There may be small black specks on the surface, which are cotton husk remnants and a sign of being unbleached. They are harmless to the body and will come off in the wash. The same fabric is used as a well-known cloth menstrual pad manufacturer. Layer 2: Breathable waterproof fabric (prevents water from passing through, but allows humidity to escape) Layer 3: Double gauze (underwear-facing side) 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). It can be used comfortably for warming activities, fertility treatments, during sensitive pregnancies, and by those experiencing menopause. #HIKARIE's Room
