南非采购需求：食用明胶、药用明胶、胶原蛋白、胶原蛋白肽、明胶片、果冻胶

I'm reaching out to inquire about your Pure Marine Collagen. We're interested in ordering a bulk quantity of 25kg. Could you please provide us with detailed information about this product? Specifically, we're curious about the pricing, available forms (e.g., powder or liquid), and any certifications you might have. Additionally, it would be great to know about your production capabilities and lead times for delivery. If you have any samples available, that would be appreciated as well. Looking forward to your prompt response with the details so we can proceed with our procurement process. Thanks!
