Clear packaging for customs? (Barbie-style)

[Bizarro Amy]

I'm working on a custom Barbie as a gift, and had a neat idea for packaging. I bought a doll that should work, and was planning to reuse the box she came with, but I realized that it's too small for what I need. Is there somewhere I can get a box similar to the larger ones some of the designer Barbies come in, other than buying another doll? It can have the Barbie logo at the bottom, but I'd prefer as plain as possible. If there's a little writing at the top, that's ok as well, because I have a header that I can glue over it.

Or, if someone still has a box for one laying around that they don't need, could I pay them to ship it to me?
