南非采购需求：眼镜框、批发眼镜框、批发太阳镜、太阳镜批发、眼镜框、设计师眼镜框

I'm looking to source black sunglasses for an upcoming project. Ideally, I need a variety of styles, including options for both casual and more sophisticated occasions. Please provide info on available designs, materials, and any special features you may offer. Additionally, I'd appreciate details on MOQs, pricing, and lead times for production. If you have any samples or catalogues, that would be great to help evaluate the options. Looking forward to hearing from you soon!
