The G-Tec-C4 is an ultra-fine rollerball pen ideal for any application where fine, precise writing is required. Also suitable for detailed illustration, graphs and drawings. The 0.4mm rollerball writes a 0.2mm line of pure vivid gel colour without spreading - thanks to the high-tech bio-polymer ink. Available in ten colours. All that - wrapped up in a good-looking crystal-clear barrel and the four best-selling colours are refillable!
Uses our customers tell us about include writing in diaries and journals; accounting; editing and proof-reading; annotations, especially bibles; cricket scoring; correcting navigation charts; filling out forms; and er.. marking up acupuncture.
Cult Pens is possibly the only place around that stocks all the colours, sells them individually and supplies refills.
The G-Tec-C4 also goes by the name Hi-Tec-C in certain other markets - same pen, same ink.
The production of a 0.4mm ball point tip has been achieved using the 3-dimples supporting system technology. In this system, the 0.4mm carbide alloy ball is mounted by making three depressions in the tip of a fine stainless steel pipe, in contrast to the traditional system of hollowing out the metal tip. Since the ball will be supported on 'points' the reduction in wear surface allows smoother rotation. The resulting stroke width is just 0.2mm.
The ink used in the G-Tec-C4 is a bio-polymer ink that uses a resin made from a micro-organism very similar to yeast. Although this ink is in a highly viscous gel form during storage, the ink viscosity reduces during the writing process due to the action of the ball rotation. The ink immediately becomes viscous again once on the paper - this special characteristic allowing a clear line without ink spreading. |
