Pop away all day with this bubble wrap keyring Bubble wrap is great for protecting packages, but if you are anything like me, the real joy when it comes to bubble wrap is popping each and every bubble. That makes this Keyring probably one of the greatest gifts you could give any avid popper. The Keyring features 8 rubbery little "bubble" buttons which you can pop away with at will. The buttons themselves have a close tactile feel to actual bubble wrap. With surprise sounds along the way, from bongs to even bodily function noises, who knows what you will hear next.
