• One Sharpie brand, Ultra fine point permanent marker.
• One cork.
• A sharp, pointed knife.
• A pair of scissors.
• One pair of Latex Gloves (optional if you're already a nasty dirty mofo).

• Disassemble the pen. Take off the bottom cap and the top where the tip of
  the pen is fastened. Remove the ink stick. It'll be a foamy-like stick with
  a tough shell around it.
• Now, if you want to keep the indelible ink from staining your hands and
  getting all over make sure to wear latex gloves. It also might be a good
  idea to lay paper down to soak up the ink.
• Carefully isolate the ink stick and cut off about a 1 to 1.5-inch length.
  This may be quite difficult to do with the knife so please make your life easier and find an old pair of scisors to cut with.
• One recommendation, if you are using latex gloves, is to squeeze out any
  ink from the large half of the ink stick, letting it drop onto and soak into
  the 1 to 1.5-inch piece. This will allow for longer operability and use of
  the device as an actual pen.
• Take the 1 to 1.5-inch ink stick and put it back in the pen at the bottom,
  pushing it all the way to the top.
• Put the tip of the pen back on making sure it slips back into the ink stick properly. 
• Next, grap the cork and cut off a 1/2-inch thick piece of the cork. Discard the rest. 
• With the bottom of the plastic casing of the pen (it should be gray in
  color) and jab the "body of the pen" down onto cork. This should leave quite
  a distinct imprint. The imprint allow you to know where to cut when you use
  the knife to cut out the small piece of cork. One word of advice, don't
  worry about cutting it too big. Do worry about cutting it too small. The
  cork will compress, within reason, to fit into the tube.
• Once you have your small pen-cork you can then force it up the bottom of
  the pen while using your best judgment where to stop. In other words, force
  the cork up to the bottom of the 1 to 1.5-inch ink stick. By sliding the
  cork up the pen it should clean up any left-over ink residue that might havenot dried yet! 
• Put all caps and ends back on and VOILA! You're done.
  *Note: (1)The more you take the bottom cap off it gets easier to do so.
• (2)The pen will write for a long time without flaw.
