I'm reaching out to request a detailed quote for D-shaped, single-piece quartz plates. It would be great if you could provide various size options available for these plates, as well as any technical specifications that might be relevant. Additionally, could you please let me know the minimum order quantity for this item? I'm also interested in understanding the lead time for production and delivery. Your prompt response will be appreciated, as we are looking to finalize our sourcing decisions soon. Thank you!
