These pens are comfortable to hold and they write well. These haven't had any problems with leaking or smudging, and there are none of those annoying skips or globs of ink on paper. These would be good for most applications, including note-taking for school or for use in the office. The 0.5mm needle tip produces vivid and clear lines, and the soft silicone grips make writing—even for long periods of time—effortless. Furthermore, the ink does not bleed or smear, which is a big plus. this is a fine product that should please most consumers who have a preference for gel pens.
