Yes! All Osorsilk products are made from ultra-luxurious 100% Pure Mulberry Silk. We use the highest grade (6A) long fiber mulberry silk, with a thickness of 22 momme and enforce the strictest quality guidelines, including non-toxic dyes.

Please feel assured that all of our products are made of 100% Grade 6A mulberry silk in China, which is safe and healthy. No chemicals are added in our production process and the use of any machinery or chemical additives that could potentially compromise the quality of our silk has been strictly forbidden to ensure the perfectly soft and smooth feel of our products. Thousands of pillowcases have been sold to our customers in 6 years and we will always provide the best products and services to our customers.

Instead of thread count, silk fabrics use momme – i.e. fabric weight to measure the quality of silk fabrics. Momme weight describes the weight of 100 yards of silk, 45 inches wide, in pounds. Higher momme means there are more strands of silk per 100 yards of fabric, therefore making the product heavier. So if we weigh that fabric, and say it’s 19 pounds, the momme would be 19-momme. The higher the momme, the higher quality and more durable the fabric is. Momme can range anywhere from 11-momme to 25-momme.
