I'm looking for more info on custom enamel pins for an upcoming project. Specifically, I'd like to know about the different styles and finishes you offer, as well as any options for size and shape customization. Additionally, if you could provide details on the materials used and any minimum order quantities, that would be really helpful. Also, it would be great to get an idea about the lead times and pricing for bulk orders. If you have any samples or a catalog of previous work, please share that too, as it'll helps me visualize the options better. Thanks for your assistance!
