Attention!! I will not negotiate prices. I will block anyone who comments. To those who are purchasing, please be sure to read my profile to prevent any trouble. From among many custom cork-based helmets, Thank you very much for viewing my cork-based helmet. I am making them using new cork-based helmets. The chin strap is secured with a magic tape. The size is free size (57cm~60cm). Shipping is free. Changing to three buttons will cost an additional 2000 yen. The PSC mark is on the underside of the visor. *Because everything is done by hand, there may be some line irregularities or scratches that occur during the work. Please consider purchasing with your understanding. *Because this is a custom paint job at a low price, I do not do any leveling or polishing. *Payment must be made within 3 days. *Shipping will be within a week after the payment notification.
