A paper-towel dispenser is a device that dispenses paper towels in a public toilet. It can either be operated by a handle or via automatic dispensation in response to a motion sensor.
These dispensers are common in North America and other western countries. They are either used to replace hand dryers or used in tandem to offer users alternatives to drying their hands. Some areas opt not to use them as towels create litter and are less environmentally friendly.
Paper
The paper in the dispenser can be white or colored. Some are similar to paper towels and have perforations to allow them to be ripped off, while others consist of stacked sheets. A third kind of paper towel is torn by an integrated blade.
