An adhesive hook is a small, often plastic or metal device designed to hold items on walls or other surfaces without the need for nails or screws. It features a sticky backing that adheres to various surfaces, making it easy to install and remove without damaging the wall. These hooks are commonly used for hanging lightweight items like keys, towels, or decorations. Adhesive hooks come in various sizes and designs, allowing for versatility in home organization. They are ideal for renters or anyone looking to avoid permanent fixtures. Many adhesive hooks can support a specific weight limit, so it's important to check the packaging for guidelines on usage.
