I purchased these about three years ago. They have pockets for tissues or non-woven fabric filters and are washable, so they're hygienic. I opened one of each to check the condition after purchase, but they are unused. No individual sales. Please consider purchasing if you understand they have been stored at home. ■ Colors 　Cashmere Heather x 2 　Ash Heather x 2 ■ Material 　100% Cotton
