GLOBBER Children's Helmet for Toddlers Pink XS/S 51-54cm Size XS/S 51-54cm Retail Price: 3900 yen + tax Features an adjustable size adjuster at the back of the head. I bought this new and kept it in the car to use when riding a bicycle. It looks a little dirty, but I only used it a few times because my child didn't like wearing a helmet. There are no falls, so I think you can use it with confidence as a helmet. Bicycle Unicycle Kickboard Roller skates Skateboard Skiing Snowboarding
