A keyboard cover is a thin, flexible layer made of silicone or plastic that fits over the keys of a computer keyboard. It serves to protect the keyboard from dust, spills, and wear while also providing a layer of comfort for typing. Many keyboard covers are designed to be removable and washable, making them easy to maintain. In addition to protection, keyboard covers often feature printed designs or colors, allowing users to personalize their devices. Some covers are specifically designed for certain models, such as those for MacBook or Windows laptops, ensuring a snug fit and easy access to all keys.
