I'm looking for a specific product that features a double ring design. The primary colors should be purple and white, as these are key to my project's aesthetic. I would like to know more about the options available within this color scheme and design. Additionally, it would be great to get details on the materials used, available sizes, and any customization possibilities. If you could provide me with pricing information and lead times for production and delivery, that would be very helpful. Looking forward to your response!
