I first saw the Jetstream BLX in a big box store, on a special Uni-ball endcap display. I immediately texted my local pen store (“I saw Uni-ball Jetstream BLX colors in an evil boxstore; when r u getting them so I can buy?”) and brought another Jetstream into my life. Would it be like the glorious Jetstream standard, or would it be a crushing disappointment like the newer color series?
In the realm of design, good work. The rubbery black body (with subtle microsparkles in the material) provides good traction for gripping, and the material has a pleasant handfeel without picking up too much debris.
The rest of the pen is either silver accents, or translucent plastic matched to the color of the refill. Love it. No complaints on style.
But I do have complaints, and unfortunately, they’re about the writing experience. You can feel ink gunking on the ballpoint tip, clogging, with results ranging from episodes of writing not being smooth (being rather jarring, jerky, uneven feeling) all the way to not even writing at all.
I don’t know what the problem is. The colors look great, but the writing is unreliable. Would a smaller tip size help? Why would it, when the 0.5mm Jetstream color series also performed poorly, and black 1.0mm Jetstreams have done just fine? Maybe that blue-black Jetstream color ink series I got so long ago was just a fluke when it comes to the behavior of Jetstream inks with colors.
Sorry Jetstream. Sorry Uni-ball. But these BLX models are terrible.
But if you want to give them a shot, I’m not stopping you. You’ll find them at many box stores and also at JetPens.
