This is a set of cotton masks: 2 for adults and 1 for children. Folded in half, the adult masks measure 15cm (height) x 12.5cm (width), and the children's masks (suitable for women with small faces) measure 13cm (height) x 11cm (width). The outer fabric is 100% cotton with a refreshing blue check pattern. The lining, from left to right in the photo, is super cool fabric and double gauze for the adult masks, and yukata fabric for the children's mask. Please note that these are handmade items, so slight variations and imperfections are to be expected.
