They say that there is no free lunch in this world, and rightly so. The Rubik’s Cube Bank is different from the rest of your coin storage facilities out there, since it is pretty self-explanatory as it will come in the form of a Rubik’s Cube, where you stash away your quarters and pennies for a rainy day. Made by Tokyo-based toy maker MegaHouse, if you want to extract your savings to fulfill a new impulse purchase, you will first have to crack your brain to solve the green side (thankfully not all six). Of course, saving money will also require you to solve the yellow side as well, so it works both ways. Good thing it is quite large at 100mm × 100mm × 100mm, making it easy to manipulate even under intense pressure when you need the money, pronto! The Rubik’s Cube Bank can be yours for around $40 after conversion.
