Overview
POSCA is described on its official site as an iconic brand whose paint marker has accompanied creativity in all its forms throughout the world for the last 30 years. Launched in the early 80s, the POSCA paint marker was an immediate success among artistic communities arising from urban cultures, especially the graffiti community, and its credibility later spread from street art to fine art, illustration, portraits and customisation. POSCA is presented as a creative tool for all materials, including plastic, wood, cardboard, paper, glass and textiles, and the brand's product lines include Posca Pastel, Posca Marqueur and Posca Pencil.
History
According to the official POSCA history page, Uni Mitsubishi Pencil was founded in Tokyo in 1886, building on traditional Japanese skills to create, manufacture and market pencils. In 1983, following nearly a century of innovations in writing instruments and coloured inks, Uni Mitsubishi Pencil created POSCA, described as a revolutionary paint marker; the very first range comprised four tips and 22 colours. The page states that the POSCA marker was launched in the early 80s and was an immediate success among artistic communities arising from urban cultures, especially the graffiti community, whose members adopted it and gave it real popularity that gradually spread beyond the urban space. It adds that exchanges between artistic communities are the source of POSCA's universal credibility, and that POSCA now drives artistic momentum among creators across media, from street art to fine art via illustration, graffiti, portraits and customisation.
