Hi All, I need some guidance. I just received a brand new fountain pen, Parson's Italix, and noticed some discoloration on the back side of the nib. I looked at it under a microscope and took a picture. It distinctly looks like corrosion and pitting which was somewhat surprising given the normal high quality of these pens. Please take a look and confirm that this is indeed pitting. Will it get worse owing to acid in inks. It is a steel nib. Should I return it? Best, Les
