Meet Butter — the shade that feels as good as it looks. Soft, warm, and quietly radiant, Butter is one of those rare neutrals that works with everything and elevates any bedroom it walks into.
Crafted from 22 momme 100% mulberry silk, this pillowcase is made in our signature boomerang shape — designed specifically for side sleepers, with a gentle curve that cradles your face, neck, and shoulder to reduce pressure and support a more comfortable sleeping position throughout the night.
The ultra-smooth silk surface creates minimal friction against your skin and hair as you move compared to traditional cotton pillowcases. Silk is also naturally non-absorbent, so your overnight skincare stays on your face where it belongs rather than soaking into your pillow. Breathable and naturally hypoallergenic, it's a beautiful choice for those with sensitive skin.
Butter pairs beautifully with warm whites, linens, terracotta, and sage — a tone that feels fresh in summer and cosy in the cooler months. Understated, elegant, and endlessly wearable.
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.
Handmade in small batches using 22 momme 6A grade mulberry silk.
Note: This pillowcase is designed to fit boomerang-shaped side-sleeper pillows — commonly called U-shaped, V-shaped, or L-shaped pillows. Please check measurements before purchasing if using with a similar-shaped pillow you already own.

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.
