This pack comes with pens in nine variations: 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.8 mm and a brush pen.
The great thing about this set is that nib thickness varies enough to tell the difference between the pens. Sure, the 0.1 and 0.2 are very close in thickness, but one can still see the minute differences between them. I am particularly fond of 0.05 mm pen. It makes it so much more interesting to draw and shade with such thin lines. I would have liked to have seen more of a difference between the 0.6 and 0.8 nibs though.
The only problem I had with this set was the brush pen. I was unable to create thinner strokes even with a very light touch.
On closer inspection, the tip of the brush nib appears to have fibres that slightly split apart. Please keep in mind that I am in no way a lettering expert, but I do feel, in my humble opinion, that this can be improved upon. If you are very much in need of a brush pen for calligraphy and lettering, perhaps buy one separately.
The Tactile Experience:
The 0.05 nib is understandably rough against paper, seeing as it is such a thin nib. The rest of the pens are smooth and rather lovely against the paper. All of the pens are comfortable to hold.
4 out of 5 stars
I would strongly recommend buying these pens for use in illustrations, drawings and paintings. The only drawback I can think of would be in terms of price. If you are working on a relatively low budget or do not require as many variations in thickness of nibs, look for a smaller set of such pens. I would also suggest looking for a brush pen for calligraphy elsewhere.
