The Metropolitan Museum of Art 100% Mulberry Silk Vintage Scarf. NWOT Printed Silk Scarfs. Measurements approximately 64”x 19” The mulberry silk thread is the strongest natural fibre in the world, making it incredibly durable. For instance, a mulberry silk fibre is stronger than a fibre of steel of the same diameter. A few other features of mulberry silk include it being 100 percent hypo-allergenic and also being odourless and not needing any "airing out" before use like some of the lower quality wild silks.
