I'm interested in learning more about your OEM expandable container houses. Could you provide me with detailed specifications, including dimensions, materials used, and potential customization options? Additionally, I'd like to know about the manufacturing lead time, minimum order quantities, and any available certifications for these products. Your prompt response would be appreciated, as I'm looking to move forward with sourcing soon! Thanks!
