Send back what you don’t want using the prepaid shipping label and mylar bag included in the box. The label is for USPS, so you can drop off the bag at the post office or blue USPS collections box.
If you’re missing the shipping label, a Rocket Scientist can easily send a new one to print via email. Bag too small? Send back returns in any packaging you'd like (even the blue box itself!)
Regarding sibling boxes: please be sure to send back the returns separately for siblings (that is, not packaged together in the same bag). Our warehouse identifies returns and attributes them to the individual orders by the order numbers on shipping labels.
