This is a standard traffic safety hat for everyday use. Essential for commuting to and from school or kindergarten. Recommended not only for elementary school students but also for children in nursery schools and kindergartens. I used it every day for a year the year before last, so there are some light black stains (photo 4). The elastic has stretched, so I tied it to use (photo 5). The material is durable, so it can still be used. Please note that it will be shipped by post.
