The Etch-A-Sketch Feature is a drawing toy that was first introduced in the 1960s. It consists of two white knobs on the front of the device which can be used to draw lines and shapes on the grey screen. The knobs are used to control the movement of a stylus that is connected to the knobs, allowing the user to create their own drawings. The knobs can also be used to erase the drawings by shaking the device. This feature has made the Etch-A-Sketch a popular toy for generations of children.
