This is a set of 6 handmade L-size masks made of 100% white cotton, designed to be worn under non-woven fabric masks. These are for those who have been wearing non-woven fabric masks for a long time and are uncomfortable with the mask directly touching their skin. High-quality, durable double gauze is used for the lining. The cover masks I made previously are currently discontinued because I can't find the same fabric. Size when folded in half: Approximately 14 x 11.5 cm Outer fabric: 100% cotton Lining: Double gauze The mask elastic uses carefully selected soft, antibacterial processed elastic. Please wash in a laundry net. Please understand that these are handmade before purchasing.
