All BONES WHEELS manufactured products are warranted against manufacturing defects for the useful life of the product. If you feel your skateboard wheels, bushings, or other BONES WHEELS products were defective, you may send it back to us, freight prepaid. We will inspect it and let you know of our findings. If we decide your returned product was defective or failed to give reasonable service, we will replace that product with a similar, available product of the same or better quality and pay for the shipping back to you. You can send in multiple products to be inspected for your return. We will evaluate each product separate and will replace any and all products found to be defective.
