Our pillowcases are hypoallergenic and made from the finest 100 percent pure charmeuse silk. Compared to cotton pillowcases, silk dries out skin and hair comparably less and are recommended by dermatologists to minimize wrinkles. Our silk is smooth and dissipates static electricity which makes it a perfect material for combating morning bed hair and frizziness. Can be hand washed but also durable enough to withstand repeated machine washing on delicate settings. Air drying is recommended as excessive heat can damage silk.
