A protective case is a covering designed to shield an object, such as a smartphone or tablet, from damage. These cases are typically made from materials like plastic, silicone, or leather, providing a barrier against impacts, scratches, and dirt. They come in various styles and sizes to fit different devices, ensuring a snug fit. Many people use protective cases to extend the lifespan of their devices, as they can prevent costly repairs or replacements. Some cases also offer additional features, such as waterproofing or built-in stands, enhancing the overall functionality of the device while keeping it safe.
