If you wants to cancel an order within 24 hours after the payment has been confirmed, you will be eligible for a full refund. It is still possible to cancel an order after 24 hours but only until when it has been shipped. If an order has been shipped, we can not cancel or modify it anymore. It will have to be returned to us once your customer received it. We will only be able to issue a partial refund covering the price of the item(s) minus the shipping fees. More details,please contact with your sales manager.
