A keyring is a small loop or ring that holds keys together, making it easier to keep them organized and accessible. Typically made of metal or plastic, keyrings can come in various shapes and sizes. They often feature decorative elements, such as charms or logos, allowing people to personalize their keyrings and express their style. In addition to holding keys, keyrings can also be used to attach other items, like flash drives or miniature tools. Some keyrings even come with added features, such as a built-in bottle opener or a LED flashlight, making them practical accessories for everyday use.
