Hand Towel (Oshibori)

Oshibori is a wet towel, hot or cold, presented to customers at restaurants. Oshibori are also used in airplanes after boarding. Its purpose is to clean one's hands before a meal. The temperature of the oshibori depends on the season: in the wintertime it is heated up and in the summer it is cooled.
Oshibori can take form in a towel or a disposable, non-woven prepackaged cloth.
