Uni-ball were established in 1887 as the Mitsubishi Pencil Company.  They originally specialised in premium wooden pencils but have now developed into a global leader in quality art and office pens. Their ranges of rollerball pens, notably the classic Uni-ball Eye, have long been renowned for smooth writing characteristics, elegant design and high quality ink. These are now joined by products such as the Jetstream range of class-leading hybrid ink pens and the highly useful PowerTank which features a pressurised refill. Their art products are a favourite among creative people, especially the POSCA paint markers which are very popular with street artists, sign writers and home crafters.
