It is a child helmet

I bought this by mistake. I thought it would be a helmet for someone in the range 7-10 years, but it is too small, so I will be returning it. However, the helmet is very cute with nice graphics, easy to adjust, and, according to the instructions, has a built in LED flasher (but I think no battery).
