I'm looking to order a custom product with the dimensions of 50.8mm in diameter and 3mm in thickness. This item is intended for the Bulldog Invitational 2026 competitive swimming event, where it will feature a specific logo that represents the event. Could you provide me with details on pricing, minimum order quantities, and available options for adding the logo? Additionally, if you have any suggestions for materials or finishes that work well for a sports event, I'd love to hear them. Looking forward to your response!
