This highly popular 164 is compact and easy to use. It's in very beautiful condition. There are no cracks, chips, or malfunctions, and no engraved name, so the condition is excellent. A new compatible ink cartridge is included. Based on the length, the fine details of the parts, and the font of the engravings, this is undoubtedly a genuine product. While many fakes and broken 164s are circulating, this 164 has been authenticated and its operation has been confirmed, so please rest assured. In the unlikely event that it is a fake, a full refund (including shipping costs) will be provided. Please note that this listing is for the pen body only. If you would like the box, please let me know, and I will include it for an additional 2000 yen.
