A mask chain is a decorative lanyard, typically a beaded or metal chain, that attaches to the ear loops of a face mask to keep it from being lost or contaminated when temporarily removed. The chain is worn around the neck, keeping the mask close and accessible, and can also serve as a stylish accessory, much like a necklace or sunglass holder. Mask chains are designed to be lightweight and comfortable for long-term wear, and their multifunctionality allows them to be repurposed for glasses or other accessories.
