I'm reaching out to inquire about your range of rings. We're interested in expanding our inventory and looking for various styles, including but not limited to both classic and modern designs. Could you provide details on your available options, including materials, sizes, and price ranges? Additionally, I'd like to know about your production lead times and any minimum order quantities you may have. Quality and craftsmanship are important to us, so any samples or images of your current inventory would be greatly appreciated. Looking forward to your prompt response so we can explore potential collaboration opportunities.
