Montblanc Fountain Pen 18K Nib "Unused, Stored Item" Vintage

Unused stored item.
This is a Montblanc 18K (750G) nib for a fountain pen.
Nowadays, most fountain pen nibs are 14K, making the supple writing feel of the expensive 18K nostalgic and rare.

A long time ago, during frequent business trips to Germany, I met a prototype production designer and craftsman for Montblanc fountain pens, and had him make two custom fountain pens using Montblanc parts.
Both pens have wooden bodies; one is made of snakewood (fine nib) and the other is made of royal oak (broad nib), and I still use them with affection.
I purchased an extra 18K fine nib, which I use frequently, and kept it unused. However, I no longer need it, so I am selling it.
For reference, the snakewood pen cost approximately ￥200,000 and the royal oak pen cost approximately ￥100,000. I will not be selling these beloved items.

The size is approximately 2.5cm in length, 62mm (tip) / 50mm (end) in width, and 0.5gr in weight.
Montblanc fountain pens have different nibs depending on the model, so please examine carefully before purchasing.
No returns or complaints will be accepted.
