Returns FAQ

How do I return my order?

You have 30 days from the purchase date to contact us so that we may be able to authorize the return of your order. Please prepare the purchase order number and contact Customer Service Department via email to request an RMA number. It is important to have this RA number written visibly on the outside of the packaging as unauthorized packages can be rejected due to internal safety reasons.

Once your order is received at our facility, you will receive a refund for the amount that was paid for the returned item itself. We will process the refund back to the original method of payment. The original shipping fee is not refundable. All merchandise must be unused and in the same condition it was received. There will be a 25% handling fee deducted if the product is deemed used or there is damaged to the product or packaging.

Do you process exchanges?

Unfortunately, Nine Stars is unable to offer exchanges. However, you are able to return your order within 30 days from the purchase date. You are also able to place a new order for the desired item before or after we have processed your pending refund, as this is processed as a separate transaction.
