The 1.75" x 1.5" x 0.5" keychain has 8 rubbery little "bubble" buttons. When you push one, you hear a little pop. Just for fun, every 100th "pop" is a silly sound such as a boing, bark, and even a few rude noises.
"And since you can easily pop (pun intended) the keychain in your pocket, you'll always have bubble wrap when you need it most (you know, like when your boss starts talking)."
