Expo pen 

Tools
 
A pair of pliers ( I used needle-nosed pliers) 
                       

Take your pliers and gently pull off the end cap, this may take some force,but don't break it. You should be able to see the ink cartridge, remove it and place the two pieces in a zip-lock bag.

First take off the cap. Then take your pliers and carefully tug on the chisel tip, as it should come off with ease. 

First, put the dullest side of the chisel tip in first.  Next, take the ink cartridge and find the side with the indentation on it. Drop that side in first. The part of the ink cartridge should have four little dent on it. Finally, you put the end cap on with some force. Now go enjoy your new and sharp expo pen!
