It is the work of Mr. Sakai Sakai, the leading guru who made hand-made ink fountain pen in the 1980's. There is a time and effort to put the ink in the dropper, but since it can print ink only when it is used, the ink can be carried without being arbitrarily released and evaporation is also prevented.
(See image 2 for usage). It is almost impossible to get this fountain pen since it is not older and seems to be making it. It only has trial writing, since it kept ink properly and kept in a special case, the state is also a pretty good gem. Although it is slightly in 14 gold plating of the pen tip, there is dullness of color. The axis color is dark green.
