Four standard nib fountain pens and three glass nib pens. My total is now around 85 standard nib pens and 8 glass nib pens. The rightmost pen is unique in that it is an “eyedropper” fountain pen. Which means, it does not have an ink filling mechanism (like cartridge or ink piston). Like we used to do in India, you just pour the ink directly into the barrel (main body of the pen).
