Filled with double-cocoon mulberry silk, the top grade of silk, and handmade by four skilled artisans for each piece, this mulberry silk-filled duvet insert stands as a beacon of luxury. With the inherent characteristics of silk, the duvet insert is supremely soft, smooth, and excels in temperature regulation.

• Fill: 100% double cocoon long-strand mulberry silk (also known as dupioni or 7A) - the most premium grade of silk
• Shell: Luxe Long-Staple Cotton with a 330 thread count and a sateen weave. Buttery smooth and extra soft  
• Differs from the Mulberry Silk-filled Duvet Insert with Organic Cotton Shell only in the shell material. A Luxe Long-Staple Cotton Shell offers a softer and silkier texture, while an Organic Cotton Shell provides a crisper and more sustainable alternative
• Tack stitch to enhance fill stability while preserving the duvet's smooth and fluffy texture
• Three loops on each side of the insert for securing with a duvet cover
• Handmade by skilled artisans with decades of experience, each fill is hand-stretched from silk cocoons and professionally layered to ensure a smooth and even distribution
• Shell and fill both surpass the strictest Class I OEKO-TEX® Standard 100 certification, tested and proven free of harmful chemicals

• Strongly recommended for use with a duvet cover
• Sun-curing recommended for daily maintenance 
• Professional dry clean
• Spot clean if necessary
