Our silk meets medical standards that most "luxury" brands ignore.

While competitors focus on marketing buzzwords, we invested in OEKO-TEX® STANDARD 100 certification—the same safety standard used for medical textiles. This certification requires independent testing for over 1,000 harmful substances, including pesticides, heavy metals, and toxic dyes that cheaper silk often contains.

Our Grade 6A mulberry silk doesn't just meet luxury standards—it exceeds pharmaceutical-grade purity requirements. This level of purity is why sensitive skin conditions improve faster with properly certified silk versus uncertified alternatives.

We use heavier, more durable silk than brands charging twice the price.

Momme weight determines silk quality more than any other factor. Our 22-momme silk weighs 37% more than the 16-momme silk used by many premium brands, including some of SLIP's products. This weight difference translates directly to durability—22-momme silk lasts 3-5 years of nightly use while lighter weights show wear within 12-18 months.

Higher momme weight provides better temperature regulation, improved moisture retention, and superior resistance to friction damage. We achieve this quality through direct manufacturer relationships, eliminating markup layers that competitors build into their pricing.

You get everything needed for total silk sleep transformation—not just individual pieces.

Our bundle addresses every friction point during sleep: facial skin (silk mask), hair protection (bonnet and scrunchies), sleep surface (two pillowcases), and travel convenience (carrying case). This systematic approach multiplies silk's benefits because cotton exposure at any point undermines the protective effect.

Partial silk adoption—like using silk pillowcases but cotton hair ties—reduces effectiveness by up to 60% according to dermatological studies. Bundle pricing eliminates decision fatigue while ensuring complete benefit realization.

You know exactly where and how your silk is made—unlike most premium brands.

We maintain direct relationships with certified mulberry farms in China's Zhejiang province, where silk production has been perfected over 5,000 years. Our manufacturing partner holds ISO certification and submits to quarterly quality audits, documentation available upon request.

This transparency ensures consistency. Brands sourcing from multiple suppliers experience quality variation between batches. Our single-source approach means your replacement orders will match your original purchase exactly, something premium brands struggle to guarantee.

We're so confident in our quality, we triple the typical return period.

Most silk brands offer 30-day returns because they know silk's full benefits become apparent after 60-90 days of consistent use. We offer 90 days because we want you to experience the complete transformation: initial comfort (week 1), skin improvement (weeks 2-4), hair health changes (weeks 4-8), and long-term sleep quality benefits (weeks 8-12).

This extended guarantee reflects manufacturing confidence that competitors cannot match. Our 90-day period actually reduces return rates to 2.1% because customers become loyal once they experience the full benefit cycle.
