希腊采购需求：防弹设备，防弹板，NIJ IV 防弹板

I'm interested in getting a quote for 4 units of your premium ballistic plates designed for enhanced protection. It's important for me to know the total cost, including any applicable shipping fees and potential discounts for bulk purchases. Additionally, could you provide information on the lead time for this order? Understanding the expected delivery timeframe will help me plan accordingly. Looking forward to your prompt response with the detailed pricing and availability. Thanks!
