<human>: My ex has a couple of binders of mine (filled with pictures) that I want back, but she lives two states away. 

I said that I would pay for the shipping (she has more things to ship back from here, so I figured she'd pay for her stuff (240+ lbs) and I'd pay for mine (2lbs max)), but I don't actually know how to go about it.  

I've been looking around and it seems like shipping labels are the way to go, but I'd rather it be something easy for her to do (she lives about 20 minutes from the nearest town) like maybe shipping a box she could put my things into? I thought that sort of thing existed, but I can't find the right keywords to find it. Maybe I made it up.

Can you condense the text into a few key points?
<bot>: I need to get shit back from my ex, is there a way to ship boxes for someone to fill and mail back prepaid?
