We accept order cancellation before the product is shipped or produced. We cannot cancel the order if the product is already shipped out. 

We accept return of products. Customers have the right to apply for a return within 14 days after the receipt of the product.
To be eligible for a return, your item must be unused and in the same condition that you received it. It must also be in the original packaging. To complete your return, we require a receipt or proof of purchase. Please do not send your purchase back to the manufacturer. 

Once your return is received and inspected, we will email you a notification of receipt.  We will also notify you of the approval or rejection of your refund. If you are approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment, within a certain amount of days.
