Pins are small, pointed objects used to fasten or attach items together. They come in various types, including safety pins, which have a clasp to prevent accidental opening, and decorative pins, often used in fashion or crafts. Pins can be made from materials like metal or plastic and are commonly used in sewing, crafting, and organizing papers. In the digital world, "pins" refer to saved items on platforms like Pinterest. Users can "pin" images, articles, or videos to their boards for easy access and organization. This feature allows individuals to curate content based on their interests and share it with others.
