I hope you can provide more details about the thread material used in your products. I'm particularly interested in knowing if it's made of cotton or if other materials are being utilized in the manufacturing process. Cotton is a key factor for us, so understanding the composition will help in making a more informed decision. If you could share any specifics about the types of threads and their properties, that would be really helpful. Additionally, if you have any certifications or quality standards related to the materials used, it would be great to have that info too. Thanks for your assistance!
