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, once a nib dipped in ink. Ruling pens permit exact accommodation of extraction width, and yet find a few specialized uses, but complex pens such as the Rapidograph are more commonly used. enlightened types affix ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main protester types of pens can be categorized by the nice of writing tip or reduction on the pen:
A ballpoint pen dispenses an oil-based ink by rolling a little difficult sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries going on for rudely on approach next paper. The ballpoint pen is usually well-behaved and comes in both inexpensive and costly types. It has replaced the fountain pen as the most common tool for undistinguished writing. (There are positive ballpoint pens combining combined colours in a single barrel; the writer or performer may sadden the tip behind the desired colour). Lszl Br patented the first commercially well-to-do ballpoint pen.
A rollerball pen dispenses a water-based liquid or gel ink through a ball tip similar 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 designed to adjoin the ease of access of a ballpoint pen subsequently the serene "wet ink" effect of a fountain pen. Gel inks are to hand in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, full of life shades, shady colors, invisible ink, see-through effect, shining colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become available 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, subsequently through the nib, due to capillary achievement and gravity. The nib has no touching parts and delivers ink through a thin slit to the writing surface. A fountain pen reservoir can be refillable or disposable; the disposable type is called an ink cartridge. A pen past a refillable reservoir may have a mechanism, such as a piston, to magnetism ink from a bottle through the nib, or it may require refilling next an eyedropper. Refill reservoirs, along with known as cartridge converters, are affable for some pens which use disposable cartridges. A fountain pen can be used next permanent 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 additional surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers taking into account wide tips and gleaming but transparent ink, called highlighters, are used to stress text that has already been written or printed. Pens intended for children or for stand-in writing (as in imitation of a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or supplementary 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 in the works more handily on dark or slick 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 gleaming or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some further form of marking or shaping, for example, in pottery. It can plus be a computer adjunct that is used to support in navigating or providing more truthfulness afterward using touchscreens. It usually refers to a narrow lengthy staff, similar to a highly developed ballpoint pen. Pens exist which contain a ballpoint tip on one end and this sort of touchscreen stylus on the other.
