I am a cancer screening lab tech who uses these pens to mark abnormal cells on glass microscope slides. My profession has been looking for a white pen that writes well on glass and fits under the objective lens of the microscope for thirty years. Finally! A pen that does the job. These are great! They mark precisely where we want and flow well. The lines show up nicely on the background of the black microscope stage. Don't ever stop making these or I'll have to retire...

Love them. So opaque....

Love them. So opaque. So nice. The only problem is that, as expected, if you use them over a medium that can bleed, it will turn that color. :c
They're also really thick and not good for super tiny detail work. I wish they had a similar pen in a smaller size, but the jellyroll pen doesn't even stand up to the opacity this pen has. The down side is that because it does use a lot of ink, they run out really fast which is why I suggest buying them in a 10 pack. I ran two out of ink just adding highlights to a 24"x16" piece. I've since bought another pack and will probably purchase more in the future.

I am a professional calligrapher and this is my go-to when I need white gel ink. It is very opaque and bright on the darkest paper. The only issues I have found...if you write too quickly the ink will occasionally "skip". It is not as free flowing as the signo gold and silver inks. And warning...this ink WILL smear on certain surfaces. I recently did an order of very high quality black envelopes with a tight,smooth finish and had to put tissue paper between each one as when they were stacked they did smudge onto the adjacent envelopes. The writing itself does not smear..but the residue did and I had to use and art eraser to get off the smudge marks. Also happened on an order of navy envelopes. Does not seem to happen on Kraft or lighter, less heavy weight paper where the ink absorbs into the paper more instead of sitting on the surface...but do beware it can and will leave white marks on some papers if they touch. Would also love to see signo design this line so that you can see when the ink is getting low in the barrel....a bit of a pain as you usually cannot use this pen until it is completely empty and it starts to "fade" in brightness about with about 1/4" ink or more left but you cannot see the ink level.

The best white ink gel pen I have ever used! I never thought I would find another white gel pen ever again. You certainly can't buy these things from your local office supply store. Thank god for Jet Pens! I thought I was going to have to start using another medium for my crafting. The ink is smooth and totally opaque. You can mix it with other colors to get the desired effect. Jet Pens has me as a customer for life!

Received my first order of Signo white ink gel pens from JetPens a week ago.
They are excellent! They are comfortable to use, and the ink flow is smooth and
bright white. I am back for more!

Best white pen on the market to write over the top of paint. Perfect for art journaling and drawing in ink. Good coverage and a nice bright solid white color.

I love these pens. Write on most everything, but leave your white gel on surface. Grest for artwork and journaling. My fav for 8+ years.

These are the gold standard in opaque, whit gel pens. The coverage is amazingly good. Not great for detail however, so I tend to use them in conjunction with either the Sakura Gelly Roll or the Uniball Signo Angelic .7mm pen.
Very nice heavy pens!...

Very nice heavy pens! The ink is opaque and goes on very smooth! The white isn't "pure" white like my heavy body white acrylic but its hardly noticeable and looks good! Again not waterproof to be careful using over wet things or when sealing your work as it will reactivate and smear as I found out the hard way. All in all though I love love love them and would definitely recommend them! The lines aren't super fine which is ok for me since I work on nice sized paper (11 x 14 and 9 x 12).
