Not to worry! If you need a return shipping label to replace a lost one, you can print out a replacement label on your account page - Simply go to Your Current Set and click Reprint shipping label on the lower left side of the screen.

If you have lost or misplaced the reusable envelope, you can place your Rocksbox with the pieces you do not want to purchase in any envelope or box in which it will fit. Then just tape the return shipping label onto the package and drop it in the mail or at a USPS drop-off location.
