Uni-ball Signo Broad UM-153 Gel Ink Pen - White Ink - 10 Pen Set

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...

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!

I just received my order and I have to say that I already love these pens! Although they didn't come in the box pictured on the site, that is of little consequence, because the pens themselves are great for the highlighting effects I need them for. Thank you for offering these great pens.

The pens themselves are great. You can write quickly with them and expect a decent line. My only complaint is that if you hold the pen at too shallow an angle, the edges of the tip will scratch/smear the ink as you write.

Other thoughts: One thing I didn't really care for is that a box is pictured. I received no such box, just 10 pens. Not a big deal... I just expected a box of pens like in the photo.
