菲律宾采购需求：翻领别针

I would like to place an order for 250 units of a specific item. The key specifications are that each piece should have a diameter of 3 cm, which is equivalent to approximately 1 1/4 inches. Additionally, it's important that the product features a double magnet on the back for optimal functionality. Please confirm the availability of these items along with the pricing and lead time for delivery. If possible, I would also appreciate any product samples or images to ensure they meet our quality standards. Looking forward to your prompt response as we are keen to move forward with this order soon.
