The Uni-Ball one gel ink uses the new bead-pack pigment technology, which has been proven effective for writing more colorful and memorable letters.

Unlike typical quick-drying ink, this newly developed Uniball One Ink adjusts the solid-to-liquid ratio to ensure quick penetration without blotting or bleed-through. It dries fast without bleeding through to the other side.
