This is an eye mask made of gentle silk material. Made in Japan and one size fits all, so anyone can use it. There is a mark where a sticker was removed. It is an unopened new item, but please refrain from purchasing if you are sensitive to it, as it has been stored at home. It is stretchy, fits well, and does not feel constricting. If it's the type that goes around the head, it can mess up your hair. This is the type with stretch lace ear straps. Silk 69% Cotton 25% Polyurethane 4% Skin side 100% silk *This is being sold as part of decluttering. It will be shipped in a slightly folded envelope. Thank you for your understanding.
