A piggy bank is a container used to store coins and small amounts of money, often shaped like a pig. Traditionally made from ceramic or plastic, piggy banks are designed to encourage saving, especially for children. They usually have a slot on top for inserting coins and a removable bottom or a plug for retrieving the saved money. Piggy banks come in various designs and sizes, appealing to different age groups and interests. They can be simple or decorative, sometimes featuring characters from popular culture. Using a piggy bank can help individuals develop good saving habits and financial responsibility over time.
