The silk is made of silk as an endogenous home textile, and the silk is more unique in quality, advantages such as warmth, fluffiness, and breathable health. In ancient times, the princes of the officials and the princes of the emperor and the relatives of the country used silk quilts. Therefore, the silk is the most comfortable quilt to cover. How is the silk washed? 1. The silk is covered with 3 layers, silk, inner sleeve and quilt cover. The silk + inner sleeve is the so-called core, which cannot be washed. The quilt cover can be removed and washed. Therefore, it is protected by the cover and it will not be dirty inside. 2. Silk is not easy to generate static electricity, so it will not absorb dust and dirt like chemical fiber and wool. It has been very clean even after using it for several years. So don't worry. 3. If the core is accidentally contaminated with stains, you can use a neutral detergent to partially wipe the low temperature drying. If you can't handle it yourself, you can go to the dry cleaner for local treatment. Pendant for Brecelets,Round Charms Pendant,Crossbones Pendant Moyu Jewelry Co., Ltd. , http://www.bl-jewelry.com
