Damages:

It is critical that you inspect the packaging of all items when they arrive and check if you received all boxes listed on the delivery receipt. If you notice any damage or shortage of packages, you must make a note of it on the bill of lading, take pictures, and refuse delivery. Your note should say "refused due to damage". If there are no damages visible before opening the box, you must note "subject to further inspection may contain concealed damage". By signing a freight delivery without making any notes, you accept the product as it is and release the seller from any liability. If you notice any damage after receiving the delivery, do not throw the box away, and contact us with the photos of all sides of the packaged goods within 2 business days. We cannot process your claim if you fail to send images within 2 business days. After we receive information from you about the refused delivery or concealed damage, we immediately initiate a claim with the shipping company or with the manufacturer. After the claim is fully processed, we ship all replacements at absolutely no cost to you.

Cancellations & Returns:

We can cancel your order at absolutely no cost to you before the shipping label or Bill of Lading has been created, or before production of a custom order has started. Custom made items are not eligible for cancellations or returns after production has started. You can return all non-custom made items within 30 days of delivery, except when noted otherwise on their product page. To be eligible for a return, the item must be unused and in the same condition as you received it. It must also remain in the original packaging, and the packaging must be in perfect resellable condition. The cost of shipping the product both ways (to the customer, and back to the warehouse) and a 25% restocking fee will be deducted from the refund. Orders delivered outside the United States are not eligible for refunds. If your order arrived damaged, "Damages" section applies. Please contact us before returning your order to discuss shipping details. All refunds will be issued to the credit card you used for your purchase within 2 days after all returned items arrived at the warehouse. If a credit card refund is not possible, we will issue a direct deposit.
