Self-adhesive retroreflective film (white) reflector Reflective stickers 85mm x 200mm x 12 sheets Reflects car lights and shines brightly in white, making it highly visible. (The second image is a photo taken with a flash.) It can alert drivers, "I'm here!" It starts to get dark around 5 PM outdoors. You can cut and apply these to bicycles, bags, etc., as a safety measure for children and family. Also, cutting and applying them to pillars in garages and parking lots can be a safety measure when entering or exiting with a car or motorcycle. For those who walk their dogs in the evening, it's also a good idea to stick a little on leashes or harnesses. #ReflectiveMaterial #SafetySupplies
