We’ve seen fake lenses that were actually thermos‘ before, so why not a Canon DSLR coin bank? It will make saving money fun again. And when you have enough saved up, you can buy the real camera. It will be a constant reminder of your goal.
The slot is small enough for both coins and folded paper currency. And don’t worry, you won’t need to smash this with a hammer to get your money out. The lens can be removed easily. Only $29.90.
