How to insert ink cartridges into Beiluner fountain pens?
Step 1     
Disassemble the Pen:
Unscrew your pen’s barrel from the feed section. 

Step 2     
Insert your cartridge:
Find the opening of the cartridge and insert it into the pen’s feed section. 

Step 3     
Press Firmly:
Push the cartridge firmly into the feed until you feel the cartridge puncture. This may take more force than you expect. You will be rewarded by a satisfying "click"! 

Step 4     
Leave the Pen Tip Down:           
It can take a while for the ink to fully saturate the pen so don’t worry if it doesn’t start writing right away. You should shake it gently if you would like to speed up the process, although this may result in a small amount of leakage or spillage.  


How to use a ink converter for bottled ink?
Step 1     
Remove the converter from the pen barrel (keep the converter and the nib on) . Twist the piston until the spring is fully down.

Step 2     
Fully insert the nib into the bottled ink.  

Step 3     
Twist the knob at the end of the converter. This moves the piston up and down, creating a vacuum that draws ink up into the pen.  

Step 4     
Once the ink is in the converter, remove nib from bottle, clean excess ink with a dry cloth and screw nib and converter back into pen barrel.
