捷克采购需求：特色产品

I'm interested in purchasing a quantity of 50 grams of your product. We are currently evaluating suppliers and would like to understand more about the specifications and quality of what you offer. It would be great if you could provide detailed information regarding the product, including any relevant certifications, pricing, and lead times for delivery. Additionally, if you have any recommendations or best practices for usage, that would be appreciated. We're looking to establish a long-term relationship with a reliable provider, so insights into your production capabilities and any minimum order requirements would be helpful as well. Looking forward to your prompt response!
