When an item sells on SidelineSwap, the seller receives a prepaid shipping label. So all the seller needs to do is print, pack and ship.

Materials You Need to Ship a Lacrosse Goalie Stick:

Packing tape
Two boxes: one long, rectangular box for the shaft; a shorter rectangular box for the head
Tape measure

How To Package:

Assemble the longer box - secure one end with at least 3 layers of tape, and leave the other end open
Secure the creases of the box with plenty of tape
If you want extra protection, fill the ends of the box with crumpled newspaper to ensure the stick is not touching the end of the box; you can also bubble wrap the stick
Place the shaft into the longer box so that the head is poking out from the top
Place the smaller box over the head
Tape up the opening between the two boxes

A new box is stronger than a used one, but if you want to go with used, you can ship your items using whatever box you can find around the house
Go to your local pro shop to ask if they have any old boxes they're no longer using
If you're using an old box, be sure to remove any old labels
Use the smallest box possible to securely ship your item
If you use USPS priority mail, the boxes will be free!
