The Boker Plus Redox Pen takes advantage of the rapid oxidation that occurs when the ethergraf tip comes into contact with paper.

Pros:

• does not wear out
• leaves no unwanted traces on hands or clothing 
• can be used without any problems even under the most adverse conditions
• can neither be erased nor wiped away
• made of high-strength titanium
• can be used as a tactical pen for self-defense

Cons:

• not suitable for recycled paper or cardboard (only white paper)
• relatively light color (low contrast)
