In December 2022, an American customer gave us an order. The customer made children's makeup. The mailer box was very beautiful. Around Christmas, the client received the mailer box. She was very happy to tell me that she was very satisfied. In March 2023, the client approached me again to make a more complex mailer box, which I actually thought was very simple for us. More uv is added in the process. We still work very hard to make pakage boxes for our customers. Despite repeated communication. Finally, when we confirmed the effect of the mailer box, we found that the external pattern of the box was not what the customer wanted. The result of the final check is that we misunderstood in the communication process. We decided to redo this batch of mailer boxes for our customers free of charge. And I think that's the kind of attitude that we're going to have to stick with for a long time.
