美国采购需求：防护防水壳、设备硬壳、防水壳、dji pocket 3 防水壳、dslr 防水壳、dslr 防水壳

I'm interested in acquiring some protective waterproof cases, specifically the hard cases designed for equipment storage and transport. To begin with, I would like to request a quote for an initial order of 10 units. Additionally, it would be great if you could provide a price for a single unit as a sample. This would allow me to evaluate the quality and suitability of the product before proceeding with a larger order. If you could also share details about the lead time for availability and any relevant shipping options, that would be much appreciated. I'm looking forward to your prompt response so we can move forward with this potential order. Thank you!
