A saving piggy bank, often simply called a piggy bank, is a small container, traditionally made from ceramic or plastic, designed to help people, particularly children, save money. It typically takes the shape of a pig with a slot on top for inserting coins or bills. Saving piggy banks serve as a simple and visual tool for teaching the importance of saving and financial responsibility. When the piggy bank is full, it can be opened to access the saved money, which can then be deposited in a bank or used for various purposes. It's a practical and educational way to instill the habit of saving money from an early age.
