Uni-ball

The Mitsubishi Pencil company was founded in Tokyo by Niroku Masaki in 1887 as the "Masaki Pencil Manufacturing Company". Masaki Pencil started to export its products, first to Mexico in 1927, then expanding to other markets including Belgium, Egypt, Portugal, Argentina, India and Netherlands. At the end of World War II, the company introduced the "9800" pencil. In 1959, Mitsubishi released its first ballpoint pen, while its first mechanical pencil was launched in 1961. In 1966, they began creating performance pens and by 1979 they developed the first "Uniball" rollerball pen, The name Kuru Toga is a portmanteau of the two Japanese words 'kuru' (turning) and 'togaru' (to be sharpened). In August 2020, Uni-ball announced a partnership with Starline. Beginning in January 2021, Starline became the exclusive supplier of the Uni-ball brand for the promotional products industry. In February 2024, the company announced it was acquiring German fountain and ball point pen company Lamy. The acquisition was completed in the same month. == Products ==

They are more permanent on porous surfaces. Poscas use water-based paints with pigments that is highly opaque, and semi-waterproof when dry. There are slight variations in colours available between the Japanese and International pens. Posca pens are popular with graffiti artists and had their origins in graffiti culture. Posca have collaborated with Japanese clothing brand Wasted Youth. The collaboration items were displayed in a pop-up gallery in Miyashita Park. Painter Ken Hamaguchi held an exhibition "Posca: The Opacity of Love 2022" (ポスカ、その愛の不透明度 2022) showcasing Posca artwork. == References ==
