I want to trade my extra Waterman Edson section/feed/nib, emerald color, bold size, just used a few times to see it's way too bold for me.

In exchange, I'd like a Waterman serenite nib unit (any size would do) to convert my rollerball into fountain pen

Best would be shipping with tracking number (I have bad issues with SAL lately).

(Attention: this is not a trade for the full Edson fountain pen but only the nib unit.)

shameless bump
