Due to the nature of our print on demand service, once an order has been submitted and the printing process has started, there is no right of cancellation or withdrawal. Since we print your order on demand, specifically for you, we are unable to accept returns or provide refund for bulk orders once they have entered the production phase. However, if there are any issues with the quality or fulfilment of your order, please contact our Customer Sales team and we will work with you to find a satisfactory solution.
