It's called "section" the final block of the tip of the pen, the one in which the nib and feeder are inserted. The figure shows the three most common types of section present on antique pens, corresponding to three different types of filling system; for more details on this type please refer to the page on "section and repair types". A further nomenclature related to the section is that of the so-called "nipple", present only on some types of section (in the figure types 1 and 2), used on pens whose filling system requires the presence of a sac, which is usually glued on the collar.

The section is present on almost all the fountain pens except for some particular designs like [[PFM]], where the nib is directly inlaid on the section and then protrude, or as in the [[Parker T1]] or the [[Pilot]] [[Murex]] where the nib is the continuation of the metal body. To these specific exceptions are added all the safety, which for construction mode do not have a section, being the nib retractable inside the body of the pen.
