You may notice that some tablet users wear drawing gloves. Sometimes these gloves even come inside the tablet box. Unlike a normal glove, usually a drawing glove only covers the last two fingers and leaves your other two fingers uncovered.
The gloves keep the screen free from sweat and oil from your hand.
Primarily they are worn by people using pen displays (tablets that have a screen) though they work just as well with pen tablets.
They can also be useful in helping with palm rejection with tablets that support touch.
Some people just wash them as laundry. Others hand wash with a mild detergent
