This is a super cool two-layer set, with a 100% cotton seersucker fabric on the front and cotton gauze on the back. The mask with the star-shaped gauze lining, folded in half, is 14 cm long and 11 cm wide. The mask with the red super cool (cools when wet) lining is 13 cm long and 11 cm wide. The outer fabric is a refreshing 100% cotton check, so it can be worn by both men and women. It's a set of two, so you can wear them as a pair. Please note that these are handmade, so there may be slight variations in size and minor imperfections.
