ABSTRACT:
A writing instrument has an inner barrel defining a compartment for storing writing leads, an outer front barrel encircling a forward portion of the inner barrel and an outer rear barrel encircling a rearward portion of the inner barrel. The outer rear barrel is angularly displaceable about the inner barrel but not axially displaceable relative thereto. An eraser holder is mounted within the rearward portion of the inner barrel and holds an elongate eraser which can be extended and retracted in response to angular displacement of the outer rear barrel in opposite directions.
