Protect your 100% Mulberry Silk Pillowcases with our Fine Mesh Laundry Bags. These bags keep your pillowcases safe through the wash, rinse, and spin cycles. Even the "gentle" setting on your washing machine can tear, twist, and snag delicate fabric. A micro-mesh laundry bag prevents damage allowing the convenience of machine washing your silks. The more you take care of your silk, the more they take care of you.
