Here's what we're sending: This item is designed to minimize differences in appearance due to the pattern. The item will be labeled as "Handkerchief" on the shipping label, 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 fabric (skin side) This set allows you to try different flannel fabrics: unbleached on both sides (photos 3 and 4 only), patterned, and colored (light pink). Layer 2: Breathable waterproof fabric (prevents water from passing through while allowing humidity to escape) Layer 3: Double gauze (underwear side) The fully waterproof design can be used for a wide range of purposes, including sweat, minor leaks, vaginal discharge, and menstruation (though we cannot guarantee against leaks due to individual differences). It can be used comfortably for warm-up activities, fertility treatments, during sensitive pregnancies, and by those experiencing menopause. #HIKARIEhandmadeRoom
