美国采购需求：金属工艺品、奖章、别针、硬币、钥匙扣、开瓶器

I'm looking to get a quote for pins that I need for an upcoming project. Could you please provide details on the different types of pins you offer, including sizes, materials, and any customization options? Additionally, it would be helpful to know about your pricing structure, minimum order quantities, and lead times for production and delivery. If you have any catalogs or samples, please include that info as well. Thanks!
