Is there anyone who doesn’t love the addicting pleasure of popping the little bubbles in bubble wrap? It would be great, if not slightly impractical, to carry around sheets of bubble wrap with you at all times to pop when you get the urge. Well you can, sort of, with the Mugen Puchi iPhone 5 Case. This case from Japan has “bubbles” on the back that you can endlessly pop at all times. Because you know you can’t resist.
