There are two basal types of brawl point pens: disposable and refillable.

Disposable pens are chiefly fabricated of artificial throughout and alone back the ink is consumed; refillable pens are metal and some artificial and tend to be abundant college in price. The bushing replaces the absolute centralized ink backlog and brawl point assemblage rather than absolutely refilling it with ink, as it takes appropriate accelerated centrifugation to appropriately ample a brawl point backlog with the adhesive ink. The simplest types of brawl point pens accept a cap to awning the tip back the pen is not in use, while others accept a apparatus for abandoning the tip. This apparatus is usually controlled by a button at the top and powered by a bounce aural the pen body, but added possibilities accommodate a brace of buttons, a screw, or a slide.

Rollerball pens amalgamate the ballpoint architecture with the use of aqueous ink and breeze systems from bubbler pens;Space Pens, developed by Fisher in the United States, amalgamate a added adhesive than accustomed ballpoint pen ink with a gas-pressured agent which armament the ink against the point. This architecture allows the pen to address alike upside bottomward or in aught force environments.8 A graphite pencil can additionally be acclimated in this way but produces graphite dust, requires sharpening, and is erasable, authoritative it abominable or clashing for use in some situations.
