The jar used to store coins is generally made of ceramic or plastic. There is a gap at the top to insert coins, and there is a larger opening at the bottom for taking out the money. Of course, there are also a large number of clay pots that are not open, and can only be smashed to take out the coins when they need to be used or when they are full.
Today’s savings tanks are made of iron, porcelain, plastic, and so on. They are made in a variety of forms, including post boxes, small houses, and televisions and small animal shapes.
General piggy banks are designed to store coins, and most are in the shape of a pig. Because pigs have a large amount of food, they are fat and round, and have the intention of recruiting money and fortune, so they have almost become the standard style of the piggy bank. People buy chubby piggy banks for children to cultivate their financial ability and develop a good outlook on wealth.
