Stone Pens

Minerals instead of plastic
 
The 10Years CytoSorb Therapy anniversary pens from PRODIR, a Swiss specialist in ballpoint pens, are made of a special material.
 
The plastic has been enriched with minerals.
This reduces the plastic content by a sustainable 60% and increases the weight by 50%.
A difference that is immediately noticeable when the ballpoint pen is taken in hand.
