捷克采购需求：其他防弹产品、产品

I'm interested in purchasing ballistic face masks that are compatible with fast ballistic helmets. Could you please provide me with detailed information about the specifications, materials used, and any certifications these masks have? Additionally, I'd like to know about the available sizes, colors, and if there are options for customization. Also, it would be great if you could share your pricing structure and any bulk purchase discounts, along with the lead time for orders. Understanding the shipping options and costs would also be beneficial. Looking forward to your prompt response. Thank you!
