These pens are great- they're reasonably priced well-built and perform well. I am accustomed to using ballpoint pens that smear quite easily but the gel in these pens dries fast enough that I seldom if ever have smears anymore. I think the matte black finish is a nice touch; they feel elegant and sleek without being too showy or unusable. I have also enjoyed having the 0.5 mm size which is nice for writing in small notebooks and drawing as both of those require a level of detail that is difficult to obtain with a 0.7 mm pen.
These pens work okay once you get the sealant off the tip but they aren't the best pens I've ever used. I haven't had them long enough to comment about longevity at this point. Overall I'm satisfied with them for cost vs value.
Wanted a pen that dryed quickly with no smear and these were perfect. The only negative is they don’t roll as smooth as a gel but will buy more in the future.
