I use these to sign my photography, works great most of the time, occasionally has an uneven flow of ink but overall works well.

Good ink flow!

The flow is very good, not looking like two white lines without white ink in the middle.

But on opening the pen didn't write correctly, it did not have the great flow signo is known for, these are very disappointing and NOT SINGO original pens.

I warmed them in my hand and still no flow.

In general, Uni-ball has great ink flowing

I've yet to come across any other whit gel pen that gives a steady flow and never clogs

These have a great flow.

These have a great ink flow and a gorgeous bright white color.

The grip is nice, the white ink flows well

I have never had white gel pens that operate so smoothly with consistent ink flow.

smooth writing with a good flow

The tip is nice and wide, so you get a better flow of ink than you do with a regular gel pen

Nice, even flow of ink.

Best flow of ink is when you don't apply a lot of pressure between pen nib and surface.

I did notice the tips cloggedand prohibited the ink to run a smooth flow

I have held on to these pens, I like how white they are and I have used them as white out on my time sheets, and I do some adult coloring, I use them in them in my books as well, the ink is not as free flowing it seems to dry on the end stopping it from flowing or it flows a little to much

Nice continuous flow of ink.

Very opaque white, good flow, fun to use over dark surfaces, or on top of watercolor for highlight

This pen has a good consistent flow, it certainly has a nice grip to it, and dries pretty quickly

Never had any issues with the ink skipping...very smooth flow.

great flow for white ink, used on dark paper tangles, highlights on colored pencil and other crafty products, have ordered again, Love them

l love how this ink flows and see the possibilities to sketching as highlights
