Do you know how to measure the prestige of a silk fabric? Silk is an incredibly fine thread that has a way to measure its quality. I t ’s called ‘momme weight’. In simple terms, momme weight describes the weight in pounds of 100 yards of silk, 45 inches wide. Many silk clothing items are about 8mm in weight. Higher quality silks are 14 to 16mm or higher. Silk with a 19 momme weight represents the best balance of strength, beauty and charm. This is why UERMI has chosen the number 19 to describe its new fragrance. UR SILK 19 is a precious and perfect balance between luxurious softness, magic and intensity.
