Mitsubishi Uni-ball ONE Series Sets Guinness Record for World’s Blackest Gel Pen

Guinness Record for World’s Blackest Gel Pen
Guinness Record for World’s Blackest Gel Pen: Here is the edited version with revised sentence structures but retaining the original meaning: Guinness World Records has recognized Japan’s Mitsubishi Uni-ball ONE series black gel pen as the world’s blackest.
When it comes to the world’s blackest paint, nothing can beat Vanta Black. However, pen gel is an entirely different matter. Thanks to an innovative type of pigment-containing particles that seal the paint inside, Mitsubishi Pencil Co.Ltd now holds the record for the blackest gel pen.
Writing on paper can reduce the gel’s penetration into paper fibers, making the color appear more saturated than other gel pens.
You may wonder, ‘What use do I have for a blacker-than-average gel pen?’, Mitsubishi Pencil Co.Ltd reportedly collaborated with Ritsumeikan University to conduct memory tests using various black gel pens. They learned that blacker characters were easier to remember.
“Comparing the memorization performance of handwritten characters with ballpoint pens of different shades, we found characters written with Uni-ball One’s dark black gel had a higher correct answer rate and recall rate than those written with general gel ink,” the Japanese company wrote in a press release.
The newly developed Uniball One gel pen alters the ratio of solid to liquid components in the gel. This lets the liquid component quickly permeate the paper surface while leaving the solid coloring material on top. Although the ink remains quick-drying, the solid components on the exterior give the writing a more saturated look.
