Uni-ball Signo Needle 0.38 Review

I am a huge fan of the Uni-ball Signo line, and the Signo RT 0.5 is my favourite gel pen body and my favourite gel ink refill (UMR-85N). In second place is the Uni-ball Signo DX (UMR-1 refill) and its less common brother: the Uni-ball Signo Needle, which is basically a Signo DX with a needle tip instead of a cone tip.

I don’t have a white gel ink fine enough for the branding on the cap, so image that it’s there.

Like the Uni-ball Signo DX the Uni-ball Signo Needle isn’t as commonly found in the wild of stationery stores as the Pilot G2 or Pilot Hi-Tech-C. It does, however, come in a wide variety of colours, and unlike the Pilot G2 doesn’t blob and smear like crazy. It also has a needle tip that doesn’t wither the moment you look at it, unlike the Pilot Hi-Tech-C. It’s a workhorse needle tip gel pen with an excellent refill that doesn’t dry out even after spending years on your desk, and allows you to use it without worrying about babying its fragile needle tip.

Comfy, reliable workhorse needle point gel pens.

I love the Pilot Hi-Tec-C but I’m well aware that I have thrown more of them away than I have been able to use (the tip bends, the ink dries up and the pen no longer writes, there are “bubbles” in the refills of the even more delicate multi-pen variants of this pen). I’ve yet to have thrown a Uni-ball Signo pen away, needle point pens included. The magic happens in the tip design, which isn’t a two part deal like in the Hi-Tech-C but rather is a DX tip that has been shaped into a needle point, as if someone had taken it between two fingers and squeezed it to form a needle tip. The result is a tip that is stronger with no weak points that are prone to bending.

The smarts are all in this pen’s tip design.

You can see the difference between the Signo Needle tip on the top, and Signo DX tip in my Spoke pen on the bottom. It’s basically the same tip just tapered more acutely.

In terms of refills, the Signo Needle uses a UMR-1ND refill, which is the same as the Signo DX’s UMR-1 refill just with a different tip attached. This means that there are very few machined pens on the market that will fit the UMR-1ND refill because of the way the front of the refill is designed. However…

The Signo Needle refill does fit the Spoke pen! This is a fun bonus of them having the same refill design as the DX (minus the tip). So now not only can you have a reliable needle point gel ink pen with a variety of refills, it will also fit one of the best machined pens on the market (at least in my opinion).

I will point out that there is a tiny gap between the pen tip and the grip if you do use a UMR-1ND refill in the Spoke pen, however, the refill doesn’t wiggle in the pen and the gap doesn’t extend into the pen body – it’s just an aesthetic thing.

Here’s a writing sample with the Signo Needle 0.38. As you can see the lines are crisp and consistent even though I’ve had some of these pens lying around my desk for years. They are a tiny bit wider than the Hi-Tech-C 0.38 lines (just as the Signo DX 0.38 lines are wider than the Hi-Tech-C but thinner than the Pilot G2 0.38).

If you’re looking for a needle tip gel ink pen and are tired of throwing out broken Hi-Tech-Cs (or don’t like their somewhat spartan pen body), give the Signo Needle 0.38 a chance. It may be slightly more expensive than a Hi-Tech-C, but it will ultimately turn out to be cheaper because you’ll have a pen that you can actually use from start to finish.
