This is a bicycle helmet from Rangs Japan. I am selling it because my child is now in upper elementary school and the size no longer fits. ◯ Size: 51-57cm * Adjustable size ◯ Color: Black ◯ Manufacturing date: 2020/11 ◯ Condition: The helmet has some scratches as it was used by my child. It has been stored indoors at home, so I think it is relatively clean. Please check the photos and purchase with your understanding.
