Pen Modding has a field of specific terminology that is used to describe or abbreviate certain elements and processes. This page aims to provide a glossary for the most common terms.

Terms

Pen Parts

Barrel

Middle section of a pen. Opaque or transparent and usually made of plastic, but rarely metal. Used as the main contributor of length to a mod.

Tip

The front section of the pen used to hold the nib in place. Made of plastic or metal, and often removable by unscrewing. Used to add weight to or extend the length of mods.

Grip

A piece of soft material, usually rubber, for the writer to hold onto. Used to provide a surface with enough friction for wipers or for appearance.

Cap

Cover for the nib of the pen. Often plastic and transparent but sometimes metal, opaque or tinted translucent. Not found on retractable pens. Used to add length to mods.

Cap Rubber

A piece of rubber-like material placed into the cap to catch the nib of the pen and prevent ink from escaping. Used in some rarer mods.

Ring

Metal or plastic ring found on some pens like Airfit. Used for mod appearance.

O-Ring

Small rubber or silicone rings that can be found in hardware stores or on Zebra Tect. Used as a substitute for small grip segments.

Inktube

Pen Characteristics

COG

Center Of Gravity, the portion of the pen that it can balance on. Often used to describe if the mod is balanced towards the COP or not.

COP

Center Of Pen, the middle of the pen decided by its Length.

Style
