Underground Boardshop does not warranty any items. The company who manufactured that particular item will handle your warranty. However, we will do whatever we can to help facilitate this for you by acting as the company that represents the product and sold it to you. If you think you have a defective product, you can contact the manufacturer directly. Each warranty is handled on a case-by-case basis. Please send us detailed pictures of the defect or damage with information on how long the product has been used and what happened. We will then pass that information along to the manufacturer to help facilitate the warranty for you.
