Question

How fountain pen is filled with ink

Answer 1

Place the fountain pen, nib first, into the bottle of ink until the nib is entirely covered . Twist the piston converter counterclockwise at the top. This forces the air out of the converter. Then twist the top of the piston converter clockwise to draw the ink up into the converter.

Answer 2

Depends. You either unscrew the pen and push the cartridge in until it pops, or you put the nib in the ink bottle and put the piston down, then rotate or pull to suck up the ink.
