Wall hooks are simple, functional devices designed to be mounted on a wall to hold or hang items such as coats, bags, towels, hats, or keys. They come in a variety of materials, sizes, and styles, making them versatile for home or office use. Common materials include metal (stainless steel, brass, or wrought iron), wood, plastic, or even ceramic, each offering its own aesthetic and durability. Wall hooks can be single or multiple hooks arranged in rows, and some models feature additional features like adjustable lengths, decorative elements, or even storage options like shelves.
