Construction
The traditional cotton swab has a single tip on a wooden handle, and these are still often used, especially in medical settings. They are usually relatively long, about six inches (15 cm). These often are packaged sterile, one or two to a paper or plastic sleeve. The advantage of the paper sleeve and the wooden handle is that the package can be autoclaved to be sterilized (plastic sleeves or handles would melt in the autoclave).
Cotton swabs manufactured for home use are usually shorter, about three inches (7.6 cm) long, and usually double-tipped. The handles were first made of wood, then made of rolled paper, which is still most common (although tubular is also used). They are often sold in large quantities, possibly 111 or more to a container.
Swab stems exist in a wide variety of colors, such as blue, pink or green. However, the cotton itself is traditionally white.
