What are Bona Notti sleep masks made of?
Bona Notti eye masks are made from 100% silk on the back and pure cotton on the inside. And, they are hypoallergenic. Each and every Bona Notti sleep mask is made like a beautiful, handmade garment for your eyes. Most other sleep masks are made with synthetic materials, which dont provide the same level of comfort and skin protection that silk does.
