The pen, uncapped. The shut-off valve is half open, as can be seen on the tail of the pen.
The clip is the only place where there is a brand engraving. However, it only means that the clip had been produced by the company Fukunaka Seisakusho.
Anyway, jumbo pens are out there and deserve some attention from all of us fond of Japanese pens. If only, because of its historical relevance.
The exposed part of the nib is 25 mm long. The feed is made of ebonite.
The pen section, from the back. The conic shape is the seat for the shut-off valve.
The pen, in summary, is a eyedropper with shut-off valve. The ink deposit is in accordance with the size of the pen—over 8 ml. The nib is a generic steel unit, gold plated, cut as a medium stub in what most likely was an after market modification. It is nicely wet and pleasant to use. But it is also a slow starter due, probably, to the absence of inner cap and to the interruption of the connection with the ink deposit –by closing the shut-off valve— when the pen is not in use.
This is not a pen to carry around. It does not fit in any pocket and few pen cases could accommodate it. So, better reserve it for domestic use.
These are its dimensions:
Length closed: 160 mm.
Length open: 140 mm.
Length posted: 201 mm (but who might want to post this pen?).
Diameter: 26 mm.
Weight (dry): 55.9 g.
Ink deposit: about 8.5 ml.
Center of mass, unposted: at 78 mm. to the nib end, dry;
at 80 mm. to the nib end, full.
Platinum pocket pen, stainless steel with black stripes – Platinum black
