Hello, we would like clear information about the product, please. Satin is a form of weaving, there is cotton satin, there is silk satin, there is polyester. . . What exactly is the content of your product? In some comments, you said that it does not contain polyester, and in some comments, you say that it does contain real silk. I know that it would not be suitable, but I wonder if something can be made from the threads left when touching silk? There is polyester, please change it to cotton, for human health, if there is polyester, it will definitely make you sweat.
