    Clear anodised parts are not chemically polished for long, resulting in a dull effect

    Silver - Etching and Type II sulphuric anodising

    Silver

    Silver anodised parts are chemically polished for a longer time that results in the base material being brighter prior to anodising

    white-custom

    More colours available including colour matching
