印度采购需求：折叠式放大镜

I'm reaching out to inquire about your Ramco black ballpoint pens. We're looking to source a reliable supplier that can provide high-quality pens for our upcoming projects. Specifically, we need to understand the variety of colors, barrel designs, and tip sizes that are available, as well as any customization options you might offer. Additionally, could you please share details about your pricing structure, minimum order quantities, and lead times for delivery? It would also be great to know about your quality control measures and any certifications you have. We're keen to establish a long-term partnership, so information on bulk order discounts would be appreciated as well. Looking forward to your prompt response!
