Thank you very much for viewing this product. This is a custom cork helmet made in the image of Nars-kun from Auto Project W. I won it at an event and tried it on, but the size didn't fit, so I'm offering it for sale. I tried it on once, but only for a short time and it's undamaged, so I'm considering it as a new, unused item. *Although it says size M, it's not written, so it's unknown. To give you an idea of the approximate size, I've measured the distance from cork to cork and will list it. Length: Approximately 23cm, Width: Approximately 18cm *Please understand this is the distance from cork to cork* *The actual dimensions for your head may differ slightly* Photos 5, 6, and 7 show the reflection clearly. It has three buttons! Please ask any questions or negotiate the price in the comments section. Shipping costs will be covered by me. Thank you very much.
