How do I return an item?

Return Policy

Original sales receipt must accompany returns.
We accept returns for refund 14 calendar days after delivery of the product. At our sole discretion after 14 calendar days, we will offer a refund. Items must be in "new, unaltered condition". Definition of new, unaltered condition is:
• -without showing signs of wear or damage in any way
• -within 14 calendar days of the delivery date (after 14 days no returns are allowed)
If an item is received damaged or is incorrectly shipped by us please contact Customer Support immediately. Items that are defective and shipped from us or items that you did not order but received from us will qualify for store credit or a cash refund.
Refunds are contingent upon inspection of item(s) once we receive it.
There is a 15% restocking fee for returned items that are not being exchanged and are not damaged. Again you MUST contact us within 14 days if you intend to return ANY item back to STM. Items returned to us AFTER 14 days and WITHOUT contacting us will NOT be accepted at STM.

Customer is responsible for all shipping costs if seller is not at fault.

Please contact us through our "Contact Us" page regarding returning an item. Thank you.
