☆☆Today's Featured Item☆☆☆ 1050 yen -> 799 yen This is a set of 10 inner masks made with two layers of high-quality bleached cotton. These sheets are designed to be placed inside your mask. Even when worn inside a disposable mask, they won't show through because they are white. Made in Japan using high-quality bleached cotton, 100% cotton. Size: Approximately 7-7.5cm x 12.5-13.5cm Each one is ironed and the four sides are sewn to prevent shape distortion. These have not been pre-washed. We recommend washing them before use. Bleached cotton is more durable than gauze, but it will soften with washing. They are durable and can be used repeatedly. It's best to stretch them out well when drying. Each one is carefully sewn, but there may be slight variations in size and slight imperfections in the stitching. Thank you for your understanding. No pets, no smokers. *For those who wish for anonymous shipping, it will be an additional 50 yen. Please comment before purchasing. Thank you.
