Easy! First, hold on to the box we shipped it in. Each package includes an envelope with a pre-paid return label, packing tape and instructions. Package your KIT in its bag and seal it in the box with the provided tape. Remove the original label or Affix the return label over the original shipping label and drop it off at a FedEx ship center or call FedEx for a pickup at 1.800.GO.FEDEX. Failure to completely remove or cover the original label can cause delays in your return.
