Once we receive your item, we will inspect it and notify you that we have received your returned item. We will immediately notify you of the status of your refund after inspecting the item.

If your return is approved, we will initiate a refund to your credit card (or original method of payment). All returns are subject to a 15% restocking fee.

You will receive the credit within a certain amount of days, depending on your card issuer's policies.

Refunds for both returned or cancelled orders are typically issued in 14-21 business days and may require 1 to 2 billing cycles to show up on your bank or credit card statement.
