I'm interested in exploring the variety of yarns your factory offers, as I'm looking to expand my product line. Specifically, could you provide detailed information on the different types of yarns available, including their compositions and any special features they might have? This will help me assess which options align best with my requirements. Additionally, I'd appreciate a breakdown of the pricing for the different yarns you carry. If there are any bulk order discounts or lead times I should be aware of, please include that info as well. Looking forward to your prompt response so we can move forward efficiently!
