One of the single greatest gifts (and curses) to anyone who is a little anal retentive is bubble wrap. Sure it’s good for protecting packages, but the real joy is popping each and every bubble. Now you can get your “bubble” on wherever you go.
Each keychain device has 8 rubbery little “bubble” buttons. They have a pretty close tactile feel to actual bubble wrap. Each time you press one, you hear a little pop. In a nutshell, that is the simple beauty of the electronic bubble wrap keychain. But there is one bonus, and here’s where the OCD can kick in a little. Every 100th “pop” is not a pop at all, but a silly sound: a boing, a bark, a rude noise, etc. What more can you ask of your keychain?
