I'm reaching out to check if your facility has stock of poly-cotton yarns that are specifically blended in the 60/40 ratio. I'm particularly interested in understanding the availability of different shades and any associated specifications you might have. My goal is to source these materials for an upcoming project, and detailed information will help me make an informed decision. Additionally, could you provide insights on the pricing, minimum order quantities, and lead times for delivery? Any relevant certifications or quality assurance processes you follow would also be appreciated. Looking forward to your prompt response so we can potentially move forward with an order.
