I'm looking to source products in black color. Please provide detailed information on the available options that you have in this specific color. It would be great if you could include details such as product specifications, sizes, and any finishes or variations available. Additionally, I'm interested in understanding the minimum order quantities, pricing, and lead times for delivery. If you have any samples or catalogs showcasing the black color options, that would be highly appreciated. Looking forward to your prompt response with the necessary details.
