I'm looking to place an order for 400 pieces of drums. It would be great if you could provide me with some more details on the specifications, available options, and your current pricing. Additionally, any info on lead times for production and shipping would be very helpful. Please let me know if there are minimum order quantities, bulk discount options, and warranty policies available. I want to ensure that I'm making a well-informed decision, so your prompt response would be appreciated. Thanks in advance for your assistance!
