Introducing the Uniball One with innovative bold and bright ink. This pigment ink is formulated to sit on top your paper rather than absorb and disappear into the paper. The result is a bold bright ink that doesn't fade.
In 2024, Uni added the previously limited edition colors to the lineup in both .38mm and .5mm: Cappuccino Brown, Mango Orange, Avocado Green, Nemophila Blue, Poppy Red, Plum Purple, and Sesame Gray. In 2025, Uni added Ramune Green, Baked Apple, Butterfly Pea Blue, and Ganache.
22 colors available in .5mm: Black, Blue, Red, Blue Black, Green, Yellow, Orange, Light Pink, Pink, Sky Blue, Cappuccino Brown, Mango Orange, Avocado Green, Nemophila Blue, Poppy Red, Plum Purple, Sesame Gray, Ramune Green, Baked Apple, Butterfly Pea Blue, and Ganache.
32 colors available in .38mm: Black, Blue, Royal Blue, Light Blue, Red, Blue Black, Green, Lime Green, Emerald, Yellow, Orange, Mandarin Orange, Baby Pink, Light Pink, Pink, Sky Blue, Bordeaux Black, Green Black, Violet, Brown Black, Cappuccino Brown, Mango Orange, Avocado Green, Nemophila Blue, Poppy Red, Plum Purple, Sesame Gray, Ramune Green, Baked Apple, Butterfly Pea Blue, and Ganache.
Black ink is available with both a black barrel or a white barrel.
The complete bundles include both the white body and black body black ink pens.
Love the array of colors. Sometimes the ink doesnt flow well but that seems to be all gel pens. The point is the size i was looking for.

The Uni-ball One pens come in nice colors. The ink is great—I haven’t had problems with skipping so far. The 0.38 mm size is perfect for writing in a diary or calendar without much space since you can write pretty small.

This pen has become my new daily pen! Highly recommend for long note taking as it dries down pretty quickly for me. Please note I’m right handed too; I can’t say how well it holds up to smudging against your wrists and the back of your hand when writing wirh your left.

Live the colors, very smooth-writing. The colors are nice and saturated, too.
