I'm interested in customizing a 3D mini helmet keychain. I'd like to know if you can provide options for various colors and designs to make it unique. Also, please let me know the available materials and if you can accommodate a specific logo or text on the keychain. Could you share details about the minimum order quantity, lead times, and pricing? It would be great to see some samples or previous work if possible. Looking forward to your response so we can move forward with this project!
