We prioritize Biocompatible Purity. Many brands use silver-ion coatings that eventually wash out and can irritate sensitive skin. We believe that top-tier Grade 6A Long-Strand Silk is naturally hypoallergenic and breathable on its own.
Most high-street brands use 19-Momme silk to cut costs. Our 22-Momme density contains approximately 20% more silk per square inch. This higher density doesn't just feel more substantial and luxurious; it provides a smoother, more durable surface that reduces sleep creases and prevents hair breakage far more effectively than thinner alternatives.
Absolutely. By eliminating chemical coatings and heavy dyes, our 100% natural Mulberry silk is the most non-reactive fabric you can sleep on. Its frictionless surface prevents the physical irritation that triggers flare-ups and ensures that your expensive nighttime serums stay on your skin, rather than being absorbed by your bedding.
No. Because our silk is 22-Momme (Denser than standard 19mm luxury brands), the fibers are too tightly woven to absorb moisture. Your expensive serums stay on your skin where they belong, maximizing your dermal recovery.
Because we use high-quality Grade 6A fibers, our silk is more resilient than mass-market versions. We recommend machine washing on a cool, delicate cycle using a pH-neutral detergent and a mesh laundry bag.
The opposite. We use surgical-precision Seams to hide all raw edges inside the case. This creates a completely flat, frictionless surface that prevents sleep creases and protects delicate skin from the irritation caused by standard overlock stitching.
You aren't just buying a pillowcase; you are investing in a Sleep Protocol. Mass-market silk is typically lower-grade (4A or 5A), thin, and processed with toxic softeners. We exclusively use the top 1% of Grade 6A Long-Strand Silk with artisan-level construction. Our pricing reflects the purity of the materials and a commitment to skin longevity that cheap alternatives simply cannot provide.
