菲律宾采购需求：珐琅别针、军徽、金属翻领别针、硬珐琅别针、软珐琅别针、运动奖章

I'm interested in exploring various packaging options for keychains. Could you please provide detailed information on the available materials, customization possibilities, and any minimum order quantities? Additionally, I'd like to know about lead times for production and shipping, as well as any pricing tiers based on order volume. Understanding these factors will help me make an informed decision moving forward. Thanks!
