Sign Pen Making Plant

Abstract

Sign pen is a sort of writing tool called marking pen. It is, together with pencil, pen, ball point p-en, and mechanical pencil, one of the most widely used writing tool. Using felt tip and oily, quick drying ink, the marking pen was put on the market in 1951 as a writing tool. This felt tip pen was called felt marker. The felt marker has a broad writing tip and is used for writing on paper as well as glass, wood, plastics, cloth, metal, painted surface, and almost any other sort of material. Moreover the writing is water-resistant and will not go out easily; therefore, it has rapidly gained popularity as a convenient marker.
