Ink Type
There are to main types of ink used in the manufacture of rollerballs.
Liquid ink (free ink)
Many consumers like the writing experience and finished result offered by traditional fountain pen ink however dislike the mess that comes with the antiquated fountain pen ink delivery system. Liquid ink rollerballs simply contain fountain pen type ink with the convenience of a rollerball.
This ink delivery system is very efficient and allows all of the ink, right down to the last drop, to be used. Most liquid ink rollerballs feature a window in the barrel so the user is able to see exactly how much ink is left.
Gel Ink As the name suggests the ink used has a gel type consistency. This thicker consistency offers a very smooth writing experience, as it not only lubricates the rolling ball, but places a lot of ink onto the page. This thicker layer of ink allows the use of very vivid and metallic ink colours which clearly stand out from the page.
Pigment ink
All our inks are pigment based which makes them highly resistant to light and water. Pigment ink contains particles which are larger in size to traditional dyestuff and breakdown more slowly. When this is exposed to light and air, only the surface is affected and the colour remains vivid. This is a must for those documents you treasure and wish to keep forever.

Ink Delivery
Ballpoint pens
Ballpoint pens, write using a ball to feed the ink from the cartridge to the page.
The main characteristic of a ball pen is the writing length, generally writing between 1500 and 3000 meters.
Rollerballs
There are two types of rollerball tip.
Cone Tipped:
The rolling ball is held in a cone shaped tip, which is accurately matched to the shape of the ball. This is ideal for high volume writing.
Needle Point Tip:
The tip is shaped so that the rolling ball is held in place by four needle points.
This reduces the friction between the ball and produces a very free flowing line.
Ideal for detailed work.
