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, like a nib dipped in ink. Ruling pens allow correct getting used to of heritage width, and still locate a few specialized uses, but mysterious pens such as the Rapidograph are more commonly used. liberal types count up ballpoint, rollerball, fountain and felt or ceramic tip pens.
The main radical types of pens can be categorized by the nice of writing tip or tapering off 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 not far off from quickly upon log on past paper. The ballpoint pen is usually reliable and comes in both reasonable and expensive types. It has replaced the fountain pen as the most common tool for unsigned writing. (There are distinct ballpoint pens combining combined colours in a single barrel; the writer or performer may distress the tip past the desired colour). Lszl Br patented the first commercially booming ballpoint pen.
A rollerball pen dispenses a water-based liquid or gel ink through a ball tip thesame 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 affix the user-friendliness of a ballpoint pen like the serene "wet ink" effect of a fountain pen. Gel inks are affable in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, animated shades, shady colors, invisible ink, see-through effect, shiny colors, and glow-in-the-dark effects. Refillable rollerball pens have recently become approachable 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, after that through the nib, due to capillary pretense 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 gone 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 past an eyedropper. Refill reservoirs, also known as cartridge converters, are easy to get to for some pens which use disposable cartridges. A fountain pen can be used taking into account enduring 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 kids 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 similar to broad tips and gleaming but transparent ink, called highlighters, are used to heighten text that has already been written or printed. Pens intended for kids or for performing arts writing (as when a whiteboard or overhead projector) typically use non-permanent inks. Large markers used to label shipping cases or further packages are usually unshakable 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 straightforwardly 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 bright or neon colors.
A stylus pen, plural styli or styluses, is a writing utensil or a little tool for some further form of marking or shaping, for example, in pottery. It can furthermore be a computer accessory that is used to incite in navigating or providing more correctness afterward using touchscreens. It usually refers to a narrow elongated staff, same to a unprejudiced ballpoint pen. Pens exist which contain a ballpoint tip on one stop and this sort of touchscreen stylus on the other.
