斯里兰卡采购需求：金属工艺品、奖章、别针、硬币、钥匙扣、开瓶器

I'm reaching out to inquire about a large order of military meals. We're looking at a total quantity of around 12,000 units. Please provide details on availability, pricing, and any bulk order discounts you may offer. Additionally, it would be great to know about the lead time for production and shipping. If you could send over any product specifications or options available, that would be really helpful for our planning. Looking forward to your prompt response!
