Thank you for your letter of March 30, 2018.<BR>I know that you are very interested in our hardware products. I have learned about our company from the Internet and sent an email to our company, hoping to buy our products and check the samples. We are also very interested in establishing a cooperative relationship with you, but we have the following requirements: first, you should clearly inform the product number of the sample to be sent; second, the sample is free of charge but should be paid first, and then deducted from the order, and the freight should be borne by yourself.<BR>
