I'm looking for detailed information regarding your wool yarn supply. Could you provide specifics on the available grades, colors, and weights you have in stock? Additionally, I'd appreciate details on your minimum order quantities and lead times for delivery. It's important for me to understand your pricing structure as well, including any bulk purchase discounts. If you have a catalog or samples, that would be helpful too. Please let me know if there are any certifications or quality standards that your products meet. Thanks!
