In the hand, this pen feels well-balanced and secure. The textured grip isn't knurled, but the grooves that reach from end to end on the grip provide a great feel and stability when writing. The overall lightness of the pen also complements the writing experience.
The real star of the show, however, is the refill that debuts alongside this pen body. This pen features a 0.28mm needle-tip refill that uses the Jetstream hybrid ink system. Uni have made a 0.38mm Jetstream refill for quite a while now, and people have been impressed by that as well.
As an aside, these ultra fine refills are probably something you already know you like. And, if you don't like them, then this one certainly won't be for you! That being said, you can swap out the refill for any size tip that works with the Jetstream multipen bodies.
