Ultra Fine Point Gel Pen Comparison

Over the past few months I’ve read a lot about how others feel that one brand of ultra fine point gel pen was better than the other. Particularly how the Pentel Slicci was better than the Pilot Hi-Tec-C. I finally acquired some Slicci pens so I could run a side-by-side test myself. For the test I also included some uni-balls, a Pilot and a Zebra just to make it interesting. I picked nib diameters that were either exactly the same size or comparable. I grouped 0.28mm and 0.3mm pens together and 0.38mm and 0.4mm pens together. I did not include the Signo bit line of pens as I have only the 0.18mm version. I did not include the Hi-Tec-C 0.5mm pen because I have way to many 0.5mm pens to run a side-by-side test. The pens that I did include in the test are listed below.

0.25mm: Pilot Hi-Tec-C; Pentel Slicci.
0.28mm – 0.3mm: Pilot Hi-Tec-C; Pentel Slicci; uni-ball Signo DX
0.38mm – 0.4mm: Pilot Hi-Tec-C; Pentel Slicci; uni-ball Signo DX; Uni-ball Signo RT Gel; Pilot G-2; Zebra SARASA Clip.

The test was short and simple. I wrote a short line of text with each pen paying attention to each pens writing characteristics. The two characteristics I was concerned with were how smooth the pen wrote and how sturdy that I felt the nib was. That’s it.

0.25mm – This test included the Pilot Hi-Tec-C and the Pentel Slicci, both in 0.25mm. Both have a needle style point and that of the Slicci was noticeably thicker than that of the Hi-Tec-C. It is also something of a hybrid being a needle point that suddenly tapers into a small conical point. Of the two the Hi-Tec-Cs nib was the most fragile. I could see it wobble and bend under the pressure of writing. Both were equally as scratchy when writing on notebook paper.

0.28mm – 0.3mm – This test included the Pilot Hi-Tec-C and Pentel Slicci, both in 0.3mm and the uni-ball Signo DX in 0.28mm. Of the 3 the Signo DX was the only completely conical point. Here the Signo DX was the scratchiest of the 3. This is really no big surprise as it has the smallest point of the three. But with its conical point it is the sturdiest of the 3. The Hi-Tec-C was the smoothest of the 3 but it had the weakest nib. Like the 0.25mm version it had a noticeable wobble under pressure.

0.38mm – 0.4mm – This test included the uni-ball Signo DX, the uni-ball Signo RT Gel and the Pilot G-2 all in 0.38mm. It also included the Pilot Hi-Tec-C, the Pentel Slicci and the Zebra SARASA Clip, all in 0.4mm. Here the smoothest pen turned out to be the Hi-Tec-C. While not the sturdiest of the nibs it felt a lot sturdier that the other 2 Hi-Tec-C nibs. The Zebra turned out to be the 2nd smoothest while the scratchiest turned out to be the Slicci. All the others were about equal in smoothness, falling below the Zebra but above the Slicci. Of course the sturdiest points were the conical points, regardless.

Bottom Line, the Sliccis have stronger tips than the Hi-Tec-Cs but are equal in smoothness, or the lack there of. The conical points were the strongest of them all with smoothness varying across the board between them. So while the Sliccis may have sturdier nibs they do not write any smoother than the Hi-Tec-Cs.
