A pen is a common writing instrument used to apply ink to a surface, usually paper, for writing or drawing. Historically, reed pens, quill pens, and dip pens were used, with a nib dipped in ink. Ruling pens permit true adjustment of lineage width, and nevertheless locate a few specialized uses, but puzzling pens such as the Rapidograph are more commonly used. campaigner types total ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main liberal types of pens can be categorized by the kind of writing tip or lessening on the pen:
A ballpoint pen dispenses an oil-based ink by rolling a little hard sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries concerning tersely upon contact next paper. The ballpoint pen is usually obedient and comes in both reasonably priced and costly types. It has replaced the fountain pen as the most common tool for unknown writing. (There are certain ballpoint pens combining combination colours in a single barrel; the writer or artist may distress the tip with the desired colour). Lszl Br patented the first commercially successful ballpoint pen.
A rollerball pen dispenses a water-based liquid or gel ink through a ball tip same to that of a ballpoint pen. The less-viscous ink is more easily absorbed by paper than oil-based ink, and the pen moves more easily across a writing surface. The rollerball pen was initially expected to augment the ease of use of a ballpoint pen gone the mild "wet ink" effect of a fountain pen. Gel inks are easy to use in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, flourishing shades, shady colors, invisible ink, see-through effect, shining colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become reachable using cartridges of fountain pen ink.
A fountain pen uses water-based liquid ink delivered through a nib. The ink flows from a reservoir through a "feed" to the nib, later through the nib, due to capillary bill and gravity. The nib has no heartwarming parts and delivers ink through a skinny slit to the writing surface. A fountain pen reservoir can be refillable or disposable; the disposable type is called an ink cartridge. A pen like a refillable reservoir may have a mechanism, such as a piston, to glamor ink from a bottle through the nib, or it may require refilling considering an eyedropper. Refill reservoirs, moreover known as cartridge converters, are straightforward for some pens which use disposable cartridges. A fountain pen can be used similar to unshakable or non-permanent inks.
A felt-tip pen, or marker, has a porous tip of fibrous material. The smallest, finest-tipped felt-tip pens are used for writing upon paper. Medium-tipped felt-tips are often used by children for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often on extra surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers considering wide tips and shining but transparent ink, called highlighters, are used to emphasize text that has already been written or printed. Pens expected for children or for the theater writing (as as soon as a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or extra packages are usually surviving markers.
A gel pen uses ink in which pigment is suspended in a water-based gel. Because the ink is thick and opaque, it shows up more helpfully on dark or sleek surfaces than the typical inks used in ballpoint or felt tip pens. Gel pens can be used for many types of writing and illustration. Gel pens often come in shining or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some extra form of marking or shaping, for example, in pottery. It can as a consequence be a computer auxiliary that is used to back up in navigating or providing more truthfulness bearing in mind using touchscreens. It usually refers to a narrow lengthy staff, same to a forward looking ballpoint pen. Pens exist which contain a ballpoint tip upon one stop and this sort of touchscreen stylus on the other.
