To the guy who is complaining about the reservoir size. It isn't that the .38 size has a smaller reservoir in particular, it's that the retractable signo's as a model have a smaller reservoir. Any size of signo DX models will have the same size reservoir. If you want .38 and still want a big reservoir go look at the .38 signo DXs. They also come in .28 and .5 btw. Anyways, the pen itself has been good to me as all the models of signo I've tried have been. Other than that sometimes not having to worry about a cap can be a good thing. Also, the grip is farther down the pen, which is better for me because I hold pens closer to the tip, which with the Signo DX model is pretty far up so I end up holding past the grip anyways.

While the 0.38mm tip writes fine lines, I am rather disappointed in the ink reservoir. If you pay close attention, the inner diameter on the refill is much smaller than most normal refillable pens which explains why these pens have such a short lifespan. The inner diameter on this refill is 2mm (approximately 3/32”) whereas other pens, like the Zebra Sarasa or the Uni-ball Signo 0.5mm, have a much wider inner diameter. These pens have a 5mm (approximately 5/32”) inner diameter, resulting in 2.5 times more ink than the Signo 0.38mm RT. It’s a great price, especially for those who love super fine tips. Me? I’ll take the extra ink with a 0.5mm tip.

I love these pens. They are by far the best pens I have ever written with. I have ordered 6 refills and I bought the pack of assorted colors because they are great. I use the different colors for taking notes at school. I like how pointy and fine they are. I have gotten other brands of 0.38 and 0.4, but this is by far my favorite.

I made a general purchase on JetPens a few years back when I first discovered the site on almost every popular line of pens and pencils and erasers they have (I tried to buy one from each line, if not at least one from each brand). I have since used them all and have discarded some of the ones that were poor quality. This pen is HANDS DOWN the best pen I've ever used. If you are a pen junkie, you know that the right pen can sometimes make you write much neater and better and this pen in my hand makes my writing look like a fancy version of microsoft word. HIGHLY recommended. I just made another purchase for a new pen and 3 refills.

This is a nice pen but it does tend to skip here and there which can be a drag, especially as a college student who takes frequent notes and only uses pens.
Compared to the Uni Signo UM-151 this is not as dark in ink color, but will not smudge as easy with highlighters right away in my experience.

I ordered this pen along with 9 others in an attempt to find a fine enough point to suit my writing style and desires. I tested this pen immediately after trying the Uni-ball Signo UM-151 Gel Pen - 0.38 mm, which is the non retractable version of the same pen, or so I thought. Perhaps it was just the pens I got, but this pen wrote noticibly thinner than the UM-151, and goes above it in the list of likely candidates to become 'my pen'. I enjoyed using this pen, and continue to carry it at work while conducting my other trials.

Not a bad pen to write with. The grip is comfy and ink comes out true black. Good quality for a cheap price!

I think this is the only pen I have used up in one semester. I absolutely loved this pen and I need to get a refill for the one I bought. It works super well for notes and homework and essays.
