Writing utensil with telescoping cap

A writing utensil with telescopic cap comprising:

• an elongate substantially cylindrical writing utensil including a proximal end and a distal end, said proximal end having substantially the same diameter as said distal end, and said distal end including a writing tip;
• a telescopic cap for capping said writing utensil's writing tip, said telescopic cap including a plurality of concentric tubular elements that telescopically slide relative to one another from an extended condition to a retracted condition and vice versa, said tubular elements having an innermost tubular element that has a closed end defining the proximal end of the telescopic cap, and said tubular elements having an outermost tubular element that has an open end defining the distal end of the telescopic cap, said outermost tubular element's open end having an inner diameter substantially the same as the diameter of said writing utensil's proximal end and distal end;
• and
• said writing utensil's proximal and distal ends disengageable or engageable in a press-fit manner into said cap's outermost tubular element's open end so that said writing utensil's distal end can be inserted into said cap's outermost tubular element's open end to cap said writing utensil's writing tip, and so that said writing utensil's proximal end can be inserted into said cap's outermost tubular element's open end with said telescopic cap extended to an extended condition to provide an elongated writing instrument.
