I'm interested in getting a quote for 350 custom finisher medals for an upcoming 5K running event in San Diego, California. The medals should be in a custom shape, measuring 3.5 inches. I'm looking for them to feature soft enamel colors and come with an antique nickel finish. Additionally, I'd like each medal to include a 1.5-inch full-color ribbon that matches the design. Could you please provide detailed pricing information, including any mold fees, shipping costs to California, and the estimated production timeline? This information will help us finalize our decision as soon as possible. Thanks!
