Thank you for viewing! Surface: 100% Japanese cotton tenugui fabric Lining: White double gauze with antibacterial and deodorant treatment Size: 13 cm vertically, 10 cm horizontally when folded in half. Standard adult size. Soft mask elastic is used, making it less likely to hurt your ears. All the masks I make have the elastic sewn on, but if you are unsure about the length of the elastic, you can also choose to have the elastic threaded through the mask without being tied, allowing you to adjust and tie it yourself. Please let me know in the comments. Please note that this product is not specifically designed for virus protection. When washing, gently hand wash with a neutral detergent for clothing, shape it, and hang it to dry in the shade. When ironing, be careful not to touch the mask elastic. There is a risk of the elastic shrinking. Ironing at high temperatures has a disinfecting effect. Each piece is carefully finished, but please understand that it is not as perfect as a ready-made product, and the pattern may appear differently from the photos due to the cutting. We can also prepare boat-shaped masks with the same fabric. Please feel free to contact us. This is the price for a set of two. Instant purchase is welcome. Thank you.
