MET's CODATRONCA aero helmet. Size: L (58-61CM). Color: White Silver/Matt Glossy Domestic genuine product, with JCF official seal. Purchased a year ago and used about 4 times, but I am selling it because I bought another helmet. Also, due to the impact of rubbing hard to remove a rust-like stain on the head, the paint has slightly discolored and peeled off... sweat. I think there is no problem with the performance. In addition, there is some dirt on the lens. I have not crashed or dropped it. Helmet bag, tags, and instruction manual are all included. Thank you.
