Need to send off some headers: What should I package them in to prevent damage?

[Rob Petrie E395]

For the box goto U-haul store they make a box that is for hanging clothes its the perfect size for most headers and they are about 8 -10 bucks if I remember right. Thats what I did the first time and then I just saved the box when they come back from getting coated to ship the next set.
