They have the 4 sided body as opposed to rounded which can feel a little awkward but does give you a little better grip, although they do have a pretty "cheap" look and feel.

The triangular shape of the pen creates a nice grip.

Grip is comfortable in hands for lots of writing.

I prefer a comfortable barrel grip or a round barrel, neither or which eat into your fingers

And the satisfying thickness of the shaft makes for a really fatigue-free grip even writing for a long time

The design of these is neat - instead of round, they are kind of triangular, so it feels like you can get a good grip on the pen

The ink does not skip, the colors are vibrant, and the grip is comfortable.

A good grip can improve our handwriting

The shape of the pen is in such a way that it gives very good grip

And the satisfying thickness of the shaft makes for a really fatigue-free grip even writing for a long time

Then they changed them to a slightly less comfortable grip, and I was sad.

This makes for an easy grip and an attractive beveled appearance.

the grip is comfortable.

Overall this a good choice for smooth writing and comfortable grip, but they will never replace my original Flexgrip pens in my heart.

Ink barrel is not perfectly and results in a better grip (at least for me).-

The more triangular shape of the barrel lets you get a better and more comfortable grip on the pen

Comfortable grip and writes smooth

I love the triangle shape grip
