美国采购需求：鲍尔环、拉西环、规整填料、陶瓷球、活性氧化铝、散堆填料

We are currently looking for a specific product that measures 3.25 inches and is made from a clear material. We have been using a similar item from Lanpack, which has been meeting our needs quite well. However, we're interested in exploring other options that could provide us with either improved quality or cost-effectiveness. Could you please provide us with detailed specifications, pricing, and availability for this size and material? Additionally, any information about minimum order quantities and delivery times would be greatly appreciated. Looking forward to your prompt response, as we aim to make a decision soon. Thank you!
