西班牙采购需求：4 英寸杯刷，研磨机用鬃毛刷，除草机割草机，钢丝刷

I'm reaching out to get some pricing information on your steel brushes. I'm particularly interested in those suitable for brush cutters and clearing saws, specifically the 6" and 8" sizes. As a small online shop based in Norway, we're looking for quality products that can meet our customers' needs. Could you provide your pricing per piece, along with any bulk purchase options you might have? Additionally, it would be great to know about your shipping terms to Norway and estimated delivery times. I'm looking forward to your response so we can explore potential collaboration.
