埃及采购需求：304不锈钢脚轮，脚轮，脚轮，重型脚轮，聚氨酯脚轮

I'm looking to place an order for stainless steel wheels in two different sizes. Specifically, I need 50 sets of wheels that are 3 inches in diameter, and another 50 sets of the same design but in a 4-inch size. Quality and durability are key factors for me, as these will be used in applications that require reliability. Could you please provide me with your available options and pricing for these wheels? If there are any variations or additional features you offer, I'd love to hear about those as well. Looking forward to your prompt response so we can move forward with this order. Thanks!
