ج:

Contact customer service and provide the order number. Unopened items can be returned or exchanged within 7 days for any reason. Free repair is available within the 1-year warranty period. For items beyond the warranty period, paid repair is available. We provide after-sales guidance in both Chinese and English throughout the process.
