Excellent criterium, very classy, very elegant (though attention to the color of "pear wood" I thought more brown-ocher, but I received it "set" of a wood really pulling a color RED WOOD ). The fact that the gum is integrated discreetly in the cap of the silver propelling pencil is a great idea.
One small problem though: the mine's size (as all mines-door E-motion range of Faber-Castell) is 1.4mm, so it is harder to find these mines in the classic trade, to write, the line sometimes becomes too thick (turn the pen or working the mine ...). A shame, anyway!
