This is a SWANS ski and snowboard helmet, a free ride model, unisex H-45RM GMR gunmetal, size M (head circumference 52cm~58cm), as seen in the photo. It's new, only tried on. According to the Amazon description, it's for adults, but it's probably for children. How about a Japanese-made helmet for your child's safety? By the way, the Amazon price is 7,920 yen. It will be shipped from Saitama, with the original box wrapped in plastic. Thank you!
