I'm looking to source a specific type of black product from your factory. Could you please provide me with detailed information on the available options, including specifications, material quality, and any certifications that might be relevant? It's important for us to understand the variations in your offerings and how they align with our project requirements. Additionally, I would appreciate it if you could share pricing details, minimum order quantities, and lead times for delivery. If there are any samples available for testing or evaluation, please let me know, as that could greatly assist in our decision-making process. Looking forward to your prompt response!
