Story Image
Our silk pillowcases are crafted from 100% Grade 6A mulberry silk, sourced from Tongxiang, Zhejiang — the silk capital of China with over 4,000 years of sericulture history. Each silkworm is fed exclusively on fresh mulberry leaves, producing the finest, most uniform silk threads in the world.
We use 19 momme silk — a weight that balances luxurious softness with durability. No chemical coatings, no artificial softeners. The smoothness you feel is the natural property of genuine long-strand mulberry silk.
Sleep wrinkles are caused by compression and friction between your face and pillow. Cotton has a surface friction coefficient of 0.7, while silk is only 0.2 — that's 70% less friction. A study in the Journal of Cosmetic Dermatology found that sleeping on silk reduces friction-related skin irritation and may help prevent sleep wrinkles. Over time, the cumulative effect of reduced nightly friction can visibly improve skin smoothness, especially around the eyes and mouth where cotton pillowcases tend to crease the skin.
Cotton absorbs moisture from your hair, leaving it dry and brittle. Silk's smooth protein surface allows hair to glide without snagging, reducing tangles, breakage, and morning frizz. This is why silk pillowcases have become a staple in hair care routines worldwide — dermatologists and hairstylists consistently recommend silk for anyone with curly, color-treated, or fragile hair. Unlike cotton, silk also doesn't absorb your hair oils and skincare products, so your treatments stay on your skin and hair where they belong.
Silk quality is measured in momme (mm), the traditional weight unit. Higher momme = denser, more durable fabric. Most pillowcases on the market use 12-16 momme, which feels thin and wears out in months. Our 19 momme silk is 25-60% denser, providing better durability and a more luxurious feel. The 6A grade is the highest quality rating, reserved for silk with the longest fibers, fewest imperfections, and best color consistency. A 6A 19mm silk pillowcase is the quality you'd find in luxury brands like Slip at $89+, but without their markup.
