A patch kit is a collection of tools and materials used to repair small holes or tears in various items, such as tires, inflatable products, or clothing. Typically, a patch kit includes adhesive, patches made of durable material, and sometimes tools like sandpaper or applicators to ensure a secure bond. These kits are commonly used in outdoor activities, such as cycling or camping, where equipment may be prone to damage. Having a patch kit on hand allows users to quickly fix issues and continue their activities without needing to replace the entire item.
