John, Now you're scaring me! Had to rush to the pen cabinet and pull out my Duofold International Pearl and Black and check it against my matching pencil. I too use Penman sapphire but in the converter. I can't visibly see any degradation in the color of the barrel or cap. I do keep it in it's wooden box in the cabinet when it is not in rotation and in a leather pen case when inked and not in my pocket. The pencil sits out on my desk all of the time ready for Crossword and Sudoku puzzles. Anyone else with any degredation of a modern Duofold Pearl and Black?
