Natural 100% Silk Bonnet: This Bonnet is not your average made with REAL 100% silk, double sided, it's made to last you quite some time(most clients replace it every 5 years). I recommend washing on delicate/warm water or hand wash with Forever Fabric or Woolite washing detergent. This Bonnet is made with durable elastic and threads handmade with love built to last for years of PROTECTION weather, outdoor, sleep and more.
