Super soft, controled ink flow, easy to change cartridge ( reausable )

Very nice, even flow.

Flow of the ink is inconsistent and becomes leaky and messy very quickly!

The ink is great, and the flow is really good, but occasionally the tip of the brush becomes split, and stuck in this position until you press it up against a surface

Beyond using an actual ink well and brush, this is by far the best go-to for a free-flow ink brush pen on the market, hands down.

Unlike the disposable version where you squeeze ink into the reservoir from the grip, this one gives a nice consistent flow of ink which makes it more predictable, but conversely you can't hold back on the ink to get dry-brush effects.

Consistent flow, durable tip.

Great control, great ink flow, excuse

I lost this about three years ago and thought about replacing it almost every month because I just loved the flow of it and the illustrations I was able to do

The Pentel ink is as black as night in a mole hole, and flows freely, as free flowing as your imagination, or as tame as calligrapher's hand

Great pen and smooth flowing ink

It has great ink flow, though you have to draw a little slow to get a crisp, thick line

Flow is good, tip is easy to control, and it holds up well for fine details

The Pentel is more compact, and in my assessment has slightly better ink flow and is a slight bit easier to control depending on what you are using it for

Love the flow of this brush pen

Very smooth flowing ink.

The synthetic bush fibers are fantastic and actually give you a lot more control of line weight and stability than a standard sable does (not to mention the perfect continuous flow)

The ink flows really well, which is a gift and a curse if you are not use to it.

Love the pen it's so smooth, flows well, and fun to draw with

Great ink flow, pointy brush for tight lines, good size for my hand.

I love the pen, it's has a VERY heavy and unbelievably smooth flow

I refill them with a syringe and use free flowing rapidograph ink

The flow is perfect and it never ever ever drips

Noticed lots of artists have this pen, while I find it convenient to have a brush pen on the go, the ink looks faded and the flow is a little moody

It's has consistent ink flow from the included cartridges at any angle and line width

great pen, love the flow of ink.

Smooth ink flow and comfort in hand.

Perfect balance of flex and spring, great ink flow, nice dark ink

With the refilling of the ink, the flow immediately improved, though I was still pushing out lots of black ink

The ink refill was easy to insert and the ink flows well - with no leakage

Nice flow, and even color.

First off, I enjoyed this brush pen much more than my last one (Bimoji brand) because I can make finer lines with it, and I found it to have a nicer, more consistent ink flow
