The Micromatic 777 75 is a fully automatic fineline pencil - it has no push button and has a system whereby lead is fed forward while writing (press the tip against the paper for more lead to push out). This is a rare and complex lead propulsion system. I tested the pencil and the lead feed mechanism is working.

Comes with original box and instructions. The pencil looks unused. I have priced it low so perhaps you can add this pencil to your collection
