The colored pens have the best fine point at only 0.3mm. The colors are wonderful and bright, the ink does not bleed, and produces a fine line that makes anything you are writing look neat. I bought these to use for school while taking notes and to underline in text books. they work great and keep everything readable, but still accentuate what I need to look at. highly recommend them, and I will be buying more once they run out.
