Meet Copper — warm, rich, and unmistakably luxurious. The Sleepy Girl Boomerang Silk Pillowcase in Copper is a bold statement colour that brings a sense of warmth and opulence to any bedroom, wrapped in the comfort of 22 momme 100% mulberry silk.
The signature boomerang shape is designed for side sleepers — cradling your face, neck, and shoulder to reduce pressure and support a more comfortable sleeping position. The ultra-smooth silk surface creates minimal friction against your skin and hair as you move through the night, a noticeable difference from traditional cotton pillowcases.
Silk is naturally non-absorbent, so your overnight skincare stays on your face where it belongs, not soaked into your pillow. The breathable, temperature-regulating fabric keeps you comfortable year-round — cool in summer, warm in winter.
Copper is a warm, striking tone that pairs beautifully with earthy, neutral, and jewel-toned bedroom palettes. Bold enough to make a statement, refined enough to feel effortlessly elegant.
Why silk? Silk's smooth surface creates far less friction than cotton as you move during sleep — helping your hair stay smooth and your skin feel comfortable when you wake up. Naturally hypoallergenic and resistant to dust mites, it's a wonderful choice for those with sensitive skin.
Made in small batches using 22 momme 6A grade mulberry silk.

Silk benefits
Healthier Hair with Silk Pillowcases
Discover the Science Behind Silk’s Hair Benefits
Silk pillowcases reduce hair frizz and breakage due to their smooth surface. Silk contains two key proteins—fibroin and sericin—that are naturally hypoallergenic and help maintain hair’s moisture balance. Fibroin provides a silky, smooth texture, while sericin acts as a protective barrier, reducing friction and preventing damage. This means less tangling, fewer split ends, and healthier, shinier hair every morning.
