【Extremely Rare, Manufacturer Overhauled, Discontinued Model】Platinum Fountain Pen 22K Showa Retro with Box

Due to a sudden move, I am reluctantly selling this 22K fountain pen that I had intended to cherish forever (T^T).

Thank you for viewing.
This is a rare vintage model (PK-22-3000) from Platinum Pen, released around 1970 (Showa 45), featuring the world's first 22K nib that has etched its name in fountain pen history.

【Highlights ??】
The biggest attraction is the 22K (22-karat gold) nib, with a purity of 91.6%. The softness and golden beauty that cannot be experienced with 14K or 18K are truly a crystallization of the technology from the golden age.

【Reliable Condition】
This particular pen is a gem that I received from a trusted previous owner, having just completed an overhaul at the Platinum Pen Co., Ltd. repair store in March 2026.
After receiving it, I only did a test writing for confirmation, then cleaned it and admired it. Despite being a vintage item over 50 years old, it still shines brightly.

? Nib: 22K (Medium point). Freshly overhauled on March 4, 2026 ??
? Mechanism: Internally cleaned.
? Design: Compact, portable short-barrel type. By posting the cap on the back, it achieves an optimal balance for writing.
? Accessories: Original box from the era (bottom box only, top is a DIY clear resin cover), ink cartridges (1 blue-black, 1 black) are included, allowing you to try two colors!
* If you would like the Repair Completion Report as proof of overhaul, please comment after purchase. I will include a redacted .
