I'm interested in sourcing exercise books for resale and would love more info on what you can offer. Could you please provide details about your product range, including different sizes, paper quality, and any customization options available? Also, let me know about your minimum order quantities and pricing structure. Additionally, it would be great to understand your lead times for production and shipping, as well as any bulk purchase discounts you might have. I'm looking for reliable suppliers who can meet my needs, so any certifications or quality assurance processes in place would also be appreciated. Looking forward to your prompt response!
