I am looking for a gently used M600 to use a as a donor pen for a binde project. I genuinely do not care if you have the box or papers as long as the pen is in good working condition and doesn't show signs of wear. And since it isn't going to keep its binde, I probably don't care what color it is.  I'd prefer a B nib, but that isn't a deal breaker if the right pen comes along. Probably prefer a US seller but that also isn't a deal breaker for the right price.

If you have a pen to offer, please send me a PM. Thanks!
