The Visofil range was introduced by Mabie Todd in response to competition from the Parker Vacumatic. The Visofil uses a similar diaphragm based system which works very well (better than the vac in my opinion). This pen has been fully serviced and it now fills and writes very nicely. The Visofil pens have a large ink capacity, an advantage which is often overlooked.
The imprint on the barrel is clear and legible and the pen is in excellent condition overall with only minor wear marks. The plating to the clip and cap ring is in good order.
The No.3 Medium writes smoothly with a light flex which is always nice to have.
