Silk Pillowcase — King | Lightest Ivory | Silkki

A king-size pillowcase in 100% mulberry silk — 22 momme weight, lightest ivory, with a fold-over envelope closure that keeps the pillow securely in place through the night. Silk on both sides. OEKO-TEX certified (HKWO 055875). Machine washable on a gentle cycle. By Silkki.

How It Improves Your Daily Life

The surface you sleep on matters more than most people realize. Cotton pillowcases, however soft, create friction against hair and skin over the course of a night — which shows up as creased skin in the morning and tangled, frizz-prone hair. Mulberry silk at 22 momme is a different material entirely: the surface is smooth enough that hair moves across it rather than catching, and skin rests against it without the compression marks that rougher fabrics leave. The lightest ivory color is warm without being yellow — it works with white, cream, and natural linen bedding without requiring a specific palette. The envelope closure keeps the pillow inside without buttons or zippers that press against the face. A single pillowcase that makes a noticeable difference to how you wake up.

Why 22 Momme Mulberry Silk?

Momme is the weight measure for silk — the higher the number, the denser and more durable the weave. At 22 momme, this pillowcase sits at the upper end of what is considered premium for bedding silk: substantial enough to hold its structure and drape over years of use, without the stiffness of heavier weights. Mulberry silk — produced by silkworms fed exclusively on mulberry leaves — is the finest grade of silk available, with a longer, more uniform fiber than wild or tussah silk. The result is a surface that is consistently smooth across the entire pillowcase, not just in the center.

OEKO-TEX Certified

OEKO-TEX certification (HKWO 055875) means every component of this pillowcase — including the silk fiber, processing, and dyeing — has been tested against and exceeds international standards for harmful substances. No heavy metals, no formaldehyde, no allergenic dyes. A certification that covers the full production chain, not just the finished fabric.

How to Use It

• Primary pillowcase — use on your main sleeping pillow; the envelope closure keeps it in place through the night
• Hair care — the smooth surface reduces friction that causes tangles and frizz, particularly for curly or color-treated hair
• Travel — folds compactly; brings the same sleep surface to hotel beds
• Gift — a premium, practical gift that gets used every night; pairs naturally with a silk eye mask or a quality sleep set
