I ahve 2x Grey, and 2x Blue Mattel JuiceBoxs brand new in the package. Here's a link for info:
http://portables.about.com/od/portablevideo/a/fljuicebox.htmI bought a bunch for my kids (and bought extras in case they destroyed theirs, but they haven't yet, lol)
Ideally, if you can find the MP3 kit for these, they make great MP3 players / digital picture frames for kids.
$10 shipped each. Discount if you buy all 4
