This is a jet helmet from the 2Rinkan original brand, MOTORHEAD RIDERS. I bought it because of its cool design. It's about 1-2 years old. I was planning to use it, but I'm currently decluttering, so please, someone, use it. It's a free size. It's labeled for 57-60cm. The product is in good condition, but to prevent swapping, please understand that it's non-returnable, non-refundable, and non-exchangeable (3N). If you can pick it up, I'll discount the shipping cost by 1000 yen. I'm in a Tokyo suburb near Saitama. Thank you.
