This is a rare and popular platinum line P164. The standard 164 has gold-plated parts, but this one has silver-colored parts. There are no cracks, chips, or malfunctions, and no engraved name. A new compatible ink cartridge is included. It is a twist mechanism. Many fake or broken P164s are circulating, but this one 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) will be provided. Please note that this listing is for the pen body only. If you would like a box, please let me know. The box in the first image (may be sold out) is available for 2500 yen. A Montblanc box, different from the one in the image, is available for 1500 yen. Also, shipping via Takkyubin Compact is available for an additional 500 yen.
