If your kids are the fans of Kamen Raider, you might want to buy this Kamen Raider ATM Bank as their birthday present. This Kamen Raider ATM Coin bank is pretty cool with the face of the hero. When you un-mask the face, you can find digital display along with some buttons and slots for inserting your coins and bills.
Also, you can get the villain version if you think the hero is too dumb for taking care of the money. The only downside is that this Kamen Raider ATM Coin bank is only capable of detecting Japanese Yen, not USD Dollar. If you plan to migrate to Japan with your kids, you can get one at Strapya World for $48.10 USD.
