The one-touch reflective band prevents accidents with its yellow fluorescent reflection. It's perfect for children going to school, nighttime running, dog walking, cycling, jogging, and can be attached to wrists, bags, and bicycles. The multi-functional heart-shaped charm with a strap is convenient. It shines brightly at night with its highly reflective material. You can hang your mask on the heart-shaped part when you want to take it off briefly. The corners are hard, so you can use them to press buttons, such as in an elevator, when you don't want to make direct contact. How about a set of two?
