A fountain pen is a Pen that, unlike its predecessor, contains an internal reservoir of liquid . The pen draws ink from the reservoir through a feed to the nib and deposits it on paper via a combination of gravity and Filling the reservoir with ink may be achieved manually, via the use of a (eyedropper) or via an internal filling mechanism which creates suction (for example, through a piston mechanism) or to transfer ink directly through the nib into the reservoir which is converter.
The majority of fountain pens (with ink cartridges) can be transformed with the right ink converters. ... While inserting the converter into the nib section of the pen, be sure that it is tightened securely. Now submerge the nib into the ink bottle.
