Miniature keys are small, often decorative keys that serve various purposes, including as collectibles or accessories. They can be made from different materials, such as metal or plastic, and are often designed to resemble traditional keys but in a smaller size. These keys may be used in crafts, jewelry, or as part of themed decorations. In some cases, miniature keys are associated with antiques or historical artifacts, representing a time when keys were more ornate and symbolic. They can also be found in keychains or as part of home decor, adding a whimsical touch to everyday items.
