ZIMASILK Pillowcase

Grade 6A is the highest quality rating for mulberry silk. It indicates that the silk fibers are long, uniform, and free of impurities, resulting in a smoother, more durable, and more lustrous fabric compared to lower-grade alternatives.

Silk is naturally less absorbent than cotton, which helps your skin and hair retain their natural moisture throughout the night. Its smooth surface also reduces friction, which can minimize hair breakage, frizz, and sleep lines on your face.

The hidden zipper is designed to keep the pillow securely inside the case without disrupting the sleek aesthetic. Because it is tucked away, you typically won't feel it while sleeping, though it is recommended to handle the zipper gently during wash cycles to maintain its longevity.

This certification means the pillowcase has been independently tested and verified to be free from harmful levels of over 100 substances known to be dangerous to human health. It ensures the fabric is safe for direct contact with your skin.

To preserve the silk's integrity, hand wash in cool water using a gentle, pH-neutral silk detergent or machine wash on a delicate cycle inside a mesh laundry bag. Always air dry away from direct sunlight to prevent the fibers from becoming brittle.
