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, Pickles, and Ganache.
23 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, Pickles, and Ganache.
