We regret to inform you that we do not offer an exchange or return policy for non-defective items. If you still wish to return some resources, kindly initiate the return delivery through a courier company and bear the shipping charges for the return shipment. Once we receive the resources and verify their condition, we will process the refund for the returned items except the shipping charges. If you wish to repurchase the resources you desire, you can place a new order at any time. Thank you for your understanding.
