Micro-tipped gel ink pens are the reason I started The Pen Addict in 2007. Once I discovered that I could get gel ink pens in sub-0.5 mm tip sizes, my mind was blown. I won’t say that I’ve tried them all over the years, but I bet I’ve come close. Needless to say, I have thoughts on the best of the bunch.
- Uni-Ball Signo DX 0.38 mm - It’s so good that I helped design an upgraded pen barrel for it. What more can I say? (Buy)
- Zebra Sarasa Clip 0.4 mm - I think you can argue for several pens in the two-spot, but the Sarasa Clip is consistently good, and a joy to use. (Buy)
- Pilot Juice Up 0.4 mm - The standard Juice has been on this list forever, but the Juice Up is better than the original in every regard. (Buy)
- Pilot Hi-Tec-C 0.3 mm - If you can put up with frequent inconsistency and finickiness, then the Pilot Hi-Tec-C will provide you the sharpest fine line on this list. (Buy)
- Uni-ball Signo RT1 0.38 mm - Signo 307 or Signo RT1, that is the question here. I like the 307 barrel better, but the RT1 has many, many more colors available, and that wins out in the end. (Buy)
(Notes: In my dream scenario, Pentel kills off the Slicci lineup, and adds a sub-0.5 mm refill to the EnerGel lineup. Preferably, in the barrel they refer to as the Euro Needle. Do that, and it would be the number two pen in this list I believe.
