There is something about popping bubble wrap that is completely addictive, for both young and old. Mugen’s Pop Pop lets you “relive” the experience of bubble popping over and over. It’s a small handheld keychain device that stimulates the strangely satisfying experience of popping plastic bubble packaging. Previously the Mugen Pop Pop was only available in Japan and was pricey to import. However now the Mugen Pop Pop costs just $5.99, making it a great stocking stuffer. It’s also available in 4 great colors including blueberry, lime, pop ice, and raspberry. Mugen Pop Pops are available at Toys “R” Us, Wal-Mart and Target.
