尼日利亚采购需求：转舌锁、执手锁、平面锁、连杆锁、铰链、搭扣

I'm reaching out to get a quote for some locks we're interested in. Specifically, we're looking for options in black color, along with the corresponding locks. Additionally, we'd like to explore the grey color variants and their locks as well. It would be great to know the specifications, availability, and pricing for both color options. Please include details regarding minimum order quantities, lead times, and any bulk pricing you might offer. If you have product samples or catalogs available, I'd love to review them to assist in our decision-making process. Looking forward to your prompt response so we can move forward quickly.
