A flyer is a printed or digital promotional material that is designed to catch the attention of potential customers and inform them about a product, event, or service. It typically includes eye-catching graphics, concise and persuasive text, and relevant contact information. Flyers are commonly distributed in public places, such as on bulletin boards or handed out on the street, to reach a wide audience. They are an effective and affordable way to advertise and generate interest in a business or cause.
