Papermate PhD pens and pencils are ergonomically designed to reduce stress on your hand when writing. To further enhance the functionality of its PhD products, Papermate has released a versatile pen that includes black and red ballpoint ink and a mechanical pencil. If you write with several instruments each day, you can cut down on the number of writing implements you carry by using a Papermate PhD Multi Pen.
Twist the upper half of the pen to the left or right to select which writing utensil you want to use. Line up the indicator mark on the silver part of the pen under the twisting top with the black dot if you want to use the black ink ballpoint, the red dot if you want to use the red ink, or the symbol of a pencil tip if you want to use the mechanical pencil.
Press down on the top of the pen when the mechanical pencil is selected, to extend a piece of lead. You might need to press down more than once to extend the lead far enough to write with comfortably. Press and hold the pen top when you are finished writing, and press the tip of the pen against a solid object to push the lead back into the pen.
Pull the cap off of the top of the pen to access the pencil eraser.
Twist the top portion of the pen fully to the left until it stops, and then continue to twist in order to separate the top and bottom portions of the pen for refilling the mechanical pencil. Pull the mechanical pencil tip out of the pen and insert a fresh 0.5mm piece of lead into the pencil tip. Reinsert the pencil tip, and screw the bottom and top portions of the pen back together.
