What is a king-size pillowcase?

A king-size pillowcase is designed to fit larger pillows, typically measuring 50cm x 90cm. It offers extra coverage for added comfort and a neat, tailored look on your bed.

Are silk pillowcases better for hair and skin?

Yes. Silk pillowcases reduce friction, helping prevent hair breakage, frizz, and “bed head.” They also help maintain skin hydration and reduce sleep lines compared to cotton pillowcases.

Can I put my silk pillowcase in the dryer?

No. To preserve the softness, sheen, and longevity of your silk pillowcase, air-dry it away from direct sunlight. Avoid tumble drying.

Why is silk better than cotton for pillowcases?

Silk is naturally smooth and gentle, reducing friction on hair and skin. It is also hypoallergenic, breathable, and temperature-regulating, making it ideal for year-round comfort.

Are mulberry silk pillowcases worth it?

Absolutely. Made from long-strand Grade A mulberry silk, they are soft, durable, and naturally hypoallergenic, offering luxury, comfort, and beauty benefits night after night.
