I'm reaching out to inquire about the availability and pricing for a bulk order of medals. We're looking to purchase 5,000 pieces for an upcoming event and would like to know the options you can offer, including any customization possibilities. Could you please provide details on the materials used, available designs, and production timelines? Additionally, if you have any minimum order requirements or potential discounts for larger quantities, I would appreciate that information as well. Thanks!
