CleanRoom pens are ideal for documentation and labelling. A pen is a common writing instrument used to apply ink to a surface, usually paper, for writing or drawing. There are different kinds of pens available. A ballpoint pen dispenses an oil-based ink by rolling a small hard sphere, usually 0.51.2 mm and made of brass, steel, or tungsten carbide. 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. 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. A felt-tip pen, or marker, has a porous tip of fibrous material. 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 clearly on dark or slick surfaces than the typical inks used in ballpoint or felt tip pens.
