(1) Quill pens (fig 1-4) (sometimes erroneously called dip pens). Load with an eye
dropper containing ink. Add a drop of ink to the hollow (well) beneath the pen point. Do not
dip the pens into the ink; never submerge the point completely. The points on quill pens may be
either stiff or flexible. Use the stiff points to draw a line of consistent weight. Use flexible
points to draw graded lines. Lineweight variations depends on the pressure applied.

(2) Reservoir pens hold the ink supply within the pen itself, normally in the pen
holder. They contain a reservoir which feeds ink to the point. Reservoir pens carry either
drawing ink or writing ink, but never both. The most common examples of reservoir pens are
fountain, ballpoint, and felt-tip pens. Fountain pens have interchangeable points and come in a
variety of shapes, sizes, and degrees of flexibility. They resemble quill pens.
