The uni-ONE rollerball looks smart and works hard. The pen contains a new and improved gel ink formula designed for rich, denser consistency when writing. This results in deep and vivid colour and a consistent written line that sits proud on the page. The retractable rollerball pen has a smooth flowing 0.5mm nib for a fine neat script. Its compact, trim build features a smart metal clip and sleek white barrel. The uni-ONE’s immaculate, contemporary design sits beautifully as part of a modern stationery collection.
