Saving your money has never been this frustrating. Introducing the Rubik’s Cube piggy bank, a head scratcher of a puzzle that requires you to solve a side in order to deposit or withdraw.

To put in money, you have to solve the green side, to withdrawn you have to solve the yellow side. This is the kind of bank you give your kid if you want them to grow up hating you.

The Rubik’s Cube piggy bank is currently sold only in Japan for around $40. Frankly, I don’t really see a market here in the US. It has a higher chance of being hammered open than solve here in the states I say.
