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. 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.

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!

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).

The white ink pen to go! So far the perfect white ink pen seems unattainable, but this one is the closest one yet. The flow can be greatly improved, specially when the pen haven't been used in a while but write on you finger with it for a bit and you'll get it flowing again. Not even close to perfect but the best one in the market so far, and I have tried a several ones. The quest continues...
