10/10 for quality n finish
Unfortunately, it didn't fit into my Jinhao 159. It was entirely my fault as I didn't check its compatibility before ordering. Quality of the converter is good and the plus point is that it has an agitator ring inside which prevents the ink hanging at the top of the converter and thus not letting the feed starve from ink. Keeping it...may be of use in some pen in future. As always, Swastik's packaging and delivery was very satisfactory.
