（This barrel is not in stock and is currently available only as a made‑to‑order item.）
This pen barrel is shaped after a katana and finished in aka-tamenuri, accented with a few gold maple leaf patterns. NFC chips are hidden in the bottom and inside the barrel, and one of the maple leaves serves as the NFC marker.
When your phone gets close, it can trigger custom actions (for example opening Spotify or another music app and playing a chosen song, sharing your contact information or email, or jumping to a specific website).
If there’s anything you’d like the NFC to do, feel free to reach out to me by email. If you want this barrel to fit a different nib, please contact me so I can confirm whether it’s possible
（Please note that aka-tamenuri shifts in color depending on the angle and lighting. It’s not a fixed, single color）
