Here's what we're delivering: This item minimizes differences in appearance due to the pattern. The item will be shipped with the product name "Handkerchief." Please feel confident in your purchase. 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 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 in the wash. This item uses the same fabric as a certain cloth menstrual pad manufacturer. Layer 2: Breathable waterproof fabric (prevents water from passing through, allows humidity to escape) Layer 3: Double gauze (underwear side) These waterproof items 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). They can be used comfortably for warming activities, fertility treatments, during sensitive pregnancies, and by those experiencing menopause. #HIKARIE's Room
