Kumi Basics is a new line of washable 100% silk bedding. All sheets, duvet covers and pillow covers are made with care from 15 mm habotai silk; composed of 18 essential amino acids and naturally hypoallergenic, inhospitable to dust mites and other allergens. Kumi Basics naturally temperate silk bedding will add the luxury of silk to your bedroom and provide year round comfort and easy care. Special bedding requires a little extra special care, but it is worth it. Sheets can be washed in cool water by hand or machine washed on the delicate cycle. We recommend using a soap made especially for silk washing such as Charlie's Soap. Never use a detergent on silk, it will reduce the sheen and damage the fabric. Fluff dry on the lowest heat setting or air dry. Imported.
