Purchased from Riding Club Crane. Used approximately 60 times by a child from around the age of 6 to 7. Professionally cleaned and inspected through Riding Club Crane and then stored. Clean, with no dust or dirt. The extension wire (part for connecting the tack to the airbag) is missing. The cylinder is included, so air transport is not possible. [Additional Information] The size is as shown in the image, but it has been slightly adjusted to allow for longer use. Therefore, the fit is practically equivalent to the next smaller size. * If you "bundle buy" with the helmet also listed separately, we will offer a 2,000 yen discount.
