Assemble the calligraphy pen. Place the rounded base of the nib into the pen holder. Carefully push the pen nib in, and stop pushing as soon as it cannot go any further. Any more force can do damage that may affect ink distribution.
Place a few drops of the ink color of your choice into a small bowl. Dip the tip of a small paintbrush into the ink, and apply the ink to the curve of the pen nib.
Drop any excess ink from the pen onto a piece of scrap paper.
Holding the calligraphy pen as you would any other pen, begin your strokes. Apply the ink gently for thin lines, and add more pressure for thicker lines. Create each form or letter with as smooth of a movement as possible.
