Diamond Medal Ring Top – Super Flex (SOLD)


Diamond Medal Ring Top – Super Flex (On Ebay)

This is a Diamond Medal ring top pen. These pens have no relation to Diamond Point pens. They were high quality pens made by National Pen out of Chicago and were sold exclusively by Sears Roebuck. The pen is in great condition. The black celluloid body looks very good. The gold filled trim shows little to no brassing. The imprints is nice and crisp. The nib is a 14kt. Singer Pitts #2. I do not know anything about these nibs, but from using it I can say that it is a high quality nib. It has some fantastic flex going from XF (0.3mm) up to 2.5mm! If it was a bit easier to flex, I’d call it a wet noodle. It writes as a wet XF that is quite smooth. It is probably the best flexing nib I am offering this week.
