Hmm, interesting. If we do another case file with a button in it we could look into it, but as it was we barely broke even on the case file. (It was a labor of love.

) If it cost extra to get buttons shrink wrapped we probably couldn't afford to do it.
(We also handed out those buttons at conventions and in that situation, having the buttons individually shrinkwrapped would be pretty inconvenient...)
Also: shrinkie dinks rock!
