This is a BELL helmet that a 5-year-old wore while riding a BMX. There are some scratches, but it's still a sturdy helmet that can be used and will protect the head well. What do you think? Size: S (52-54cm) It has the rider's signature on it, but I will sell it as is. As shown in the third image, the top screw is missing. Comes with the box, bag, and instruction manual. Thank you for looking.
