Silk protein is to soak cloth and other materials with water soaked in silk, and the sanitary towel made is called silk protein sanitary towel-it's a completely stealing concept! It is not much different from ordinary sanitary napkins!
Silk sanitary napkins do have many benefits and uses, but silk protein is a deceptive cover! And there are almost no silk sanitary napkins, because you need patent authorization, no one will be stupid enough to have a patent for you to make!
