In September last year, we had a new customer who needed to order our Shark Light toy. He was used to put it in the supermarket. So we need to provide paper cards to hang on the display frame and not be too assured of the quality of our product. So, let us send samples and our original packing first. Look at the quality first. After that, the customer received the sample, felt very good, let us help them to design the card, and then communicate with the customer, confirm the paper model, and finally pay the deposit.
