OUR QUALITY IS IN THE DETAILS: Expertly crafted of the finest 100% Grade 6A 22 momme Mulberry silk. Finished with French seams for added durability and a color-matched, hidden zipper closure, our silk pillowcases provide a luxurious night's sleep. PROTECTIVE HAIR CARE: The soft, lustrous charmeuse weave of our mid-weight, breathable 22mm silk fabric is gentle on all hair types and minimizes friction to reduce breakage, frizz, and tangles. ENHANCE YOUR SKIN CARE ROUTINE: Silk naturally helps skin retain precious moisture, keeping skin hydrated and allowing your nightly skin care regimen to work as it should. By not pulling on skin, silk also helps to reduce sleep wrinkles for a rejuvenated, ready-to-go morning. NATURALLY SAFE: Our pure silk pillowcases are all OEKO-TEX STANDARD 100 Certified and colored only with environmentally-friendly dyes. Naturally resistant to common allergens, silk is an ideal option for those with allergies or skin sensitivities.
