OGK KABUTO Bicycle Helmet for Children PINE For Infants (Head Circumference: 47-51cm) SG Certified Purchased this March and used it for about six months. I'm selling it because my child quickly outgrew it. The rubber on the back has stretched a little. Other than that, there are no noticeable stains, scratches, or dents, and I think it's still in good condition and can be used for a while.
