Enter the drawing for children 9 years you see below Sorry, we just need to make sure you’re not a robot. For the comic, see Ink Pen. A pen is a writing instrument used to apply ink to a surface, usually paper, for writing or drawing. A ballpoint pen dispenses an oil-based ink by rolling a small hard sphere, usually 0.
2 mm and made of brass, steel, or tungsten carbide. The ink dries almost immediately on contact with paper. 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 combine the convenience of a ballpoint pen with the smooth “wet ink” effect of a fountain pen. A fountain pen uses water-based liquid ink delivered through a nib. The ink flows from a reservoir through a “feed” to the nib, then through the nib, due to capillary action and gravity.
The nib has no moving parts and delivers ink through a thin slit to the writing surface. A felt-tip pen, or marker, has a porous 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 children for coloring and drawing. A gel pen uses ink in which pigment is suspended in a water-based gel.
A stylus pen, plural styli or styluses, is a writing utensil or a small tool for some other form of marking or shaping, for example, in pottery. A dip pen usually has no ink reservoir and must be repeatedly recharged with ink while drawing or writing. The dip pen has certain advantages over a fountain pen. The ink brush is the traditional writing implement in East Asian calligraphy.
The body of the brush can be made from either bamboo, or rarer materials such as red sandalwood, glass, ivory, silver, and gold. A quill is a pen made from a flight feather of a large bird, most often a goose. Quills were used as instruments for writing with ink before the metal dip pen, the fountain pen, and eventually the ballpoint pen came into use. Quill pens were used in medieval times to write on parchment or paper. A reed pen is cut from a reed or bamboo, with a slit in a narrow tip. Its mechanism is essentially similar to that of a quill.
