HOW TO FILL A FOUNTAIN PEN:
Xezo fountain pens are very flexible as they have a convertible system for filling with either bottled ink or an ink cartridge. Many people prefer the convenience of an ink cartridge while others enjoy the ritual of filling their pens from the glass bottles of richly colored ink. That's why Xezo offers two options for refilling a fountain pen.

Ink Cartridges

One ink cartridge has been included in this writing set. The cartridge should only be replaced when ink supply has been depleted.

Unscrew the barrel of the fountain pen and remove the empty cartridge. Insert the narrower end of the new cartridge into the back of the section block with enough pressure to create a snug fit. The pin inside the section block will puncture the seal of the cartridge, allowing ink to flow into the section block. Screw the barrel on over the cartridge into the section block. 

Unscrew the barrel of the fountain pen and remove the empty cartridge (if present). Insert the end of the enclosed converter with the open ring into the back of the section block with enough pressure to create a snug fit. Twist the black knob end of the converter to send the piston down to the end inserted into the section block.

Dip the nib of the fountain pen into the bottled ink so that the nib is submerged up to the section block. Twist the black knob end the opposite direction to draw ink up into the converter. Remove the nib from the bottled ink and twist the black knob end a little to force out a couple of drops of ink back into the bottle. Twist the knob end again in the opposite direction to draw a little air into the converter. Screw the barrel on over the converter into the section block.
