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, as soon as a nib dipped in ink. Ruling pens allow correct becoming accustomed of heritage width, and still locate a few specialized uses, but complex pens such as the Rapidograph are more commonly used. forward looking types adjoin ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main radical types of pens can be categorized by the kind of writing tip or reduction upon the pen:
A ballpoint pen dispenses an oil-based ink by rolling a small difficult sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. The ink dries just about suddenly on open afterward paper. The ballpoint pen is usually honorable and comes in both reasonably priced and expensive types. It has replaced the fountain pen as the most common tool for mysterious writing. (There are clear ballpoint pens combining multiple colours in a single barrel; the writer or artist may afflict the tip gone the desired colour). Lszl Br patented the first commercially well-off 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 meant to combine the ease of understanding of a ballpoint pen considering the serene "wet ink" effect of a fountain pen. Gel inks are approachable in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, vibrant shades, shady colors, invisible ink, see-through effect, shining colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become handy 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, next through the nib, due to capillary undertaking 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 considering a refillable reservoir may have a mechanism, such as a piston, to fascination ink from a bottle through the nib, or it may require refilling behind an eyedropper. Refill reservoirs, moreover known as cartridge converters, are welcoming for some pens which use disposable cartridges. A fountain pen can be used subsequently steadfast or non-permanent inks.
A felt-tip pen, or marker, has a leaky tip of fibrous material. The smallest, finest-tipped felt-tip pens are used for writing on paper. Medium-tipped felt-tips are often used by kids for coloring and drawing. Larger types, often called "markers", are used for writing in larger sizes, often upon further surfaces such as corrugated boxes, whiteboards and for chalkboards, often called "liquid chalk" or "chalkboard markers". Markers like broad 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 substitute writing (as taking into account 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 stirring more helpfully upon 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 arrive in gleaming or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some new form of marking or shaping, for example, in pottery. It can as a consequence be a computer adjunct that is used to help in navigating or providing more truthfulness subsequent to using touchscreens. It usually refers to a narrow extended staff, same to a unbiased ballpoint pen. Pens exist which contain a ballpoint tip on one stop and this sort of touchscreen stylus upon the other.
