At Suzhou Ultimate Sealing Technology Co.,Ltd., the freight of sample is collected. If we have some products in stock, we can offer one or two samples for free. But the international express freight is even more expensive than our samples. We are afraid that we can not pay the freight for you. But if you are satisfied with our samples and place an order, we can offer a discount to you. And if you are ordering a relatively large quantity of customized samples, we can cover the freight.
