德国采购需求：配件、产品

I'm reaching out regarding a product that caught my attention. I'm looking for a round, black variant with a diameter of 88mm, matching the design shown in the attachment. Could you provide some detailed pricing options for this item? Additionally, please include any potential discounts for bulk orders, as well as the shipping costs to Germany. It would be helpful to know the expected lead time for production and delivery, along with payment terms. If you have any recommendations for similar products that might fit my needs, please share those as well. Looking forward to your prompt response!
