【Delivering this】 This item minimizes differences in image due to the pattern. The item will be shipped with the item name "Handkerchief". Please purchase with confidence. This is a set of 3 fully waterproof items made with carefully selected Japanese materials. Size: Approximately 22cm (length) x 17cm (width) (slight variations possible) Layer 1: Unbleached double-sided flannel (skin side) Unbleached double-sided flannel is a gentler fabric than regular products. There may be 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. Layer 2: Breathable waterproof fabric (prevents moisture from passing through, allows humidity to escape) This item uses the same fabric as a certain cloth menstrual pad manufacturer. Layer 3: Double gauze (underwear side) This waterproof type can be used for a wide range of purposes, such as sweat, minor leaks, vaginal discharge, and menstruation (due to individual differences, we cannot guarantee against leaks). You can use it comfortably for warm-up activities, fertility treatments, during sensitive pregnancies, and for those experiencing menopause. #HIKARIE's Room
