This calligraphy pen with a flat nib allows you to produce beautiful lettering with very little practice. Pen Touch comes in brilliant opaque metallic gold or silver ink, which dries quickly on paper, and is permanent on most surfaces, including plastic, wood, glass, and metal. The medium point produces a 5 mm line, with a fiber nib cut into a rectangular block. The fine point makes a 1.8 mm line, with a nib made from a special plastic so that it will not split or fray. The pens are xylene-free and low in odor.
