南非采购需求：实用防水盒、耐冲击盒、防压盒、定制防水盒、电子旅行盒、手表硬盒

I'm looking to source 10 units of a high-quality utility case that offers waterproof, crushproof, and high-impact protection. This product is essential for safely storing and transporting sensitive equipment, so durability and reliability are key. Could you provide me with details on the available options, including pricing, lead times, and any customization possibilities? Additionally, I'd appreciate any information on warranty and return policies for this type of case. Thanks!
