For factories that aim to customize leather cases with comfortable wearing experience and satisfactory quality, in addition to the continuous improvement of product quality and scheduled shipment with the changing market, the comfort of product wearing also needs to be considered. Upon receiving the customized goods as scheduled, Runqi's worry free production only requires customers to complete the sample signing of the leather cover product, and the rest is waiting for inspection and receipt. The quality is produced according to the sample, and any discrepancies can be refunded, making customers more confident and at ease. This is the direction of Runqi's efforts.
