This white ink is very thick and opaque and doesn't smear after it dries

The ink doesn't flow well and doesn't seem to be entirely opaque (sometimes appearing grayish because it's not blocking out the black color below it).And the worst part is that the tip "cuts" through its own ink, leaving a blank line where the tip was, with two white streaks on either side of that blank line

In general, Uni-ball has great ink flowing

The ink is smooth and thick

Once the ink begins to flow the lines are very clean and nice, but if you are inking on a dark paper ( like black tan etc.) be careful because the pen takes a few strokes to really start writing.

They didn't skip at all through the whole "sketch" process, they dried quick enough to where the rollers didn't smear the ink (although I was using the 'limit back and forth movement as much as possible' option to give it as much time as possible to dry), the quality of the sketch/ink is great!The ink appeared to be wet for a few seconds, but even after it was dry it was slightly shiny,

Though Sakura's brand is not terrible I always find it hard to apply the ink with them, but with these pens it glides over the paper so easily and the ink is so nice

The grip is nice, the white ink flows well

Pure white opaque ink

I love these pens!! =)RECOMMEND if you want pens that:-have smooth even ink flow 90% of the time-have even ink flow 90% of the time-are very opaque ink-show up even on pastel paper!-are fine enough for small details-don't mind waiting 1-2 minutes to dry [depends on how much ink you use]I WOULD NOT RECOMMEND if you want pens:-for very fine details

The white ink was bright enough to be seen on a white background as well.

The ink is opaque and works so well on dark paper.

I bought a pen locally and thought it must be bad ink, so I ordered these

The ink is nice and opaque and one coat does the trick for coverage

Beautiful ink

Smooth, thick ink flow

Such bright white ink!

They're the best white ink pens I've ever used for art.

They surprised me at how well they work, especially considering some of the negative reviews talk about how their ink isn't consistent, is too thin, or dries up

These work remarkably well over really dark black inks

great quality - fluid, thick white ink.

Vivid ink smooth writing

Best white ink pen I've ever used, hands down.

But do not write over other dark ink writings as the white ink will absorb the color underneath, which taints the initial color.

Use these for ink drawing nice to use for highlights and if I accidentally make a mistake

The ink is extremely smooth to the point where writing with it can actually improve my handwriting quite a bit

Though the ink takes a few seconds to dry or will smear/wipe away.

The color is so bright and the ink is nice and thick!

I wish they made an iridescent/glittery white ink pen as well

These are the best white ink pens available

smooth ink flow-opaque writing-feels sturdy and high quality

The ink runs to much for what I need it for and it bubbles up on the page rather then sinking into the paper so if you run a finger over it you can feel it

Beautiful ink flow

Covers ink well for embellishments.

The ink is smooth and consistent with a bold line

The ink didn't flow well from the American version, and just looked like a washed-out white, not bright white like it should be.

Very smooth ink and perfect for adding highlights into artwork!

Does not always completely cover if the ink is ball point or some other "messy" ink

The ball is smooth and the ink is thick and consistent the flow is one of a kind

Exactly what I was looking for in white gel ink - this is a pure white ink.

I've been looking for a great white inked pen for a while now and a friend recommend these

First, is that the ink is hard to get out sometimes

Amazing pens and the ink comes out smooth without too much pressure

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

This pen has the best opaque white ink I've come across in 20 years

With the Gelly Roll it would skip frequently and when I went over another area again, it would always scratch the ink already in the process of drying

What can I say, they're the best white ink pens I've tried

Also, if you mess up, you can easily scratch the ink off once it is dry

They write so smoothly and then ink is pretty pigmented, perfect for hand lettering :)

These are the best white ink pens I have because of the PIGMENT ink

I like it was kind of drying for my taste(not literally) the ink came out too slowly for me but cool for small projects

This pen is my favorite white-ink pen

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

The ink rolls smoothly and provides decent coverage on opaque paper, but most ink and paint bleeds through underneath it making it difficult to create opaque lines in mixed media

These are my favorite white ink pens

Fantastic, strong ink that isn't runny like Sakura gel pens.

but I thought I was purchasing white pens with dark ink

But I'm not sure it qualifies as ink

I don't want to run out of this high coverage, smooth inking white gel pen!

Beautiful ink

The ink last longer than this pen, doesn’t clog and almost as opaque

Fantastic opaque ink

The ink is good and opaque

When you are writing or covering stuff the ink is good but when it dries the white doesn't give good coverage​ at all

Absolutely amazing the ink is sooo bright and white especially on tan paper

the ink goes on so nicely, not transparent in the least.

Probably my favorite white gel ink pens

It's truly the best white ink pen i have owned and used

but I find the ink in this flows better and doesn't clog, and it lays down smoothly

so it's not ideal for super small details, but the ink itself runs smooth and fills well.

They write as well as any pen and the ink dries fast.

Nice gel ink

The ink dried just fine and didn't smear

Good ink flow!

Rolls nice, opaque ink, just wish they lasted longer, as I've gone though over 30 now

I've been searching high and low for a reliable and opaque white ink pen

Ink pours out heavy (love this)

Nice at first, but soon stopped producing solid ink lines; always had a line in the middle

good white ink.

The ink is excellent though and the pen doesn't get as clogged up as others

These are excellent white ink pens, and I use them often in my pen and ink art

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

The point was a bit broader than expected but the ink is great.

Perfect white ink pens for art work and/or writing.

The ink is nice and thick and is great for highlights in drawings

Ink is smooth, consistent and opaque

Love these pens....great ink coverage.

The ink looks great on dark backgrounds as well

They write smooth and the ink is pretty.
