Dino Salvatico wants to be sure your efforts to save money are successful; to recover your cash, his 'Bunker' bank made of cement and glass fiber must be shattered with a hammer.
I'm all for piggy banks that don't make it easy to recover your money. After all, a piggy bank that lets you easily access your savings is more of a temporary holding location than an actual vault.
Dino Salvatico specializes in industrial object design; this 'Bunker' bank certainly fits that bill. It's not in production, although it should be.
