新加坡采购需求：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 looking to explore the range of keychain options available from your factory. It would be great if you could provide detailed information regarding the various designs, materials, and customization options you offer. Additionally, I'd like to know about pricing, minimum order quantities, and any lead times for production. If you have a catalog or images of your keychains, that would be very helpful. Looking forward to your response!
