I'm interested in your high-performance alloy wheels from Rayone's Off-Road line, specifically looking for the elegant six-spoke design. I'd like to know the pricing details for the size 18/9.5. Additionally, it would be great if you could provide information on any available finishes or customization options for these wheels, as I'm keen on finding the best match for my project. Could you also let me know the lead time for production and shipping? I'd appreciate any insights on bulk order discounts as well. Looking forward to your prompt response so I can move forward with my purchasing decision.
