It's important to inculcate the habit of saving money in kids, the earlier you do it, better it is. Nothing can beat a piggy bank when it comes to solving this purpose.

But the piggy bank on the right seems to be suitable for grown up kids who have patience of leaving it closed till it is not filled. The reason for this is the convenient way of taking the money out.
You just have to remove the nose and it's open, while they can put the money inside through the snout.
