N087 Materials: While the base material is often pure silk, other materials may be mixed in. This is due to the items being sold in bulk, so please understand this before purchasing. As I am not a professional, I may not be able to answer detailed questions about the products. Please refrain from purchasing if you are seeking perfect condition items or are overly concerned about details. I will respond quickly, politely, and with sincerity. Thank you for your understanding.
