越南采购需求：塑料硬壳，塑料盒，防水壳，防水相机壳，防水 airpod 壳，防水壳

I am looking to purchase a total of 12 units of two specific product types. For one type, I need 4 pieces in black color with a sucking feature, and for the other type, I require 8 pieces also in black with the same functionality. Could you please provide the pricing details for these items? Additionally, I'd appreciate any information regarding your lead times and available shipping options. If there are any minimum order quantities or bulk discounts, please let me know as well. Looking forward to your prompt response!
