Rubik's Cube Bank -

Saving money is hard enough and the Rubik’s Cube Bank makes it a little bit trickier to go raiding your piggy bank. It looks just like a normal Rubik’s cube with a slot in the top for your coins. And it does in fact work just like a normal Rubik’s cube. But if you want to get your coins out, without taking the ol’ screwdriver to it, you’re going to have to work for it. You need to solve the yellow side to get your money out.

Luckily you don’t have to solve all six sides. Great for people who are good savers but not so good at puzzles. It sells for $40 in Japan. And no, taking the stickers off isn’t going to get you the money either.
