### ⭐⭐⭐⭐⭐ Review
*by M***W on 13 June 2025*

I actually love these pens. I have been using Jetstream pens for close to twenty years now, and usually don't like gel pens at all, but I liked the look of these ones so I figured I'd try them out. These are now my main pens, they write very smooth, the ink dries quickly, it's a good black ink too. The pen body is comfortable, the clip is easy to use. And the refills fit in a bunch of other pen bodies so I have one in one of my Alpha Gel pen bodies, and it's great.
