What are the differences between the old felt-tip and newer rollerball sections?
August 7, 2001 First, know that both these sections may be used in place of the fountain pen section. But the older felt-tip section (shown on the right) has a chrome ring around a tip that has a larger opening than the newer rollerball section due to the relatively thicker felt tip refill. Also notice that the rollerball section is slightly longer at the tip to accommodate the rollerball refill..
