Size: Length: Approximately 13.5cm Width: Since it's three-dimensional, it's about 22cm at the height of the nose. Please check the size. Inner Mask Outer fabric: Blue check 100% linen Inside: Sarashi (bleached cotton fabric) 100% cotton The part of the mask that touches the skin is made of a smooth, natural material for comfort. It's made thin, so it can be used for virus protection, inside a non-woven mask. Because it's a cool and refreshing material, you might find it more comfortable to wear than just a non-woven mask. It also helps save on non-woven masks! Smaller and larger sizes are also available. If you wish, please let me know. If you'd like, I can include two mask strings. They are made of knit fabric and won't dig into your ears. Orders placed by 4 PM will be shipped the same day. #LinenMaterial #SummerInnerMask #InnerMaskForMen #LargeInnerMask
