南非采购需求：无檐便帽，时尚配饰，羊毛无檐便帽

I'm looking for a product with dimensions of approximately 28 by 24 cm in a sleek black finish. Can you provide details on the available options, including material, durability, and any variations in design? Additionally, it would be great to know the pricing for bulk orders and estimated lead times for delivery. If you have any suggestions or recommendations based on these specs, I'd love to hear them. Looking forward to your prompt response!
