Dear Customer, We would like to extend our sincere apologies for the inconvenience you have encountered. We have reviewed the entire communication process. At the time of our quotation, we clearly stated in writing that the sample would be "sample without logo". Before you confirmed the sample order, we further confirmed with you: "Yes, the sample is in a blue box without a logo," and received your clear response of "Okay". Nevertheless, we still regard you as a valued customer and have arranged for our designers to provide you with free-of-charge vector logo optimization and 3D rendering production services. Finally, we would like to reiterate our commitment to all customers: for any quality issues caused by us, we will take full responsibility and provide a full refund. Thank you for your understanding.
