The M200 in Blue Marbled is one of early Pelikan purchases being in my collection some seven years and four months. The Blue Marbled is one of only two pens in my collection (M205 Yellow Demo being the other) that I choose to use with the J.Herbin 1670 sparkily inks.
The M250 14K 1.1mm Music nib arrived in my possession the very same day as the M200 pen above. Used today for the 20th time today it is a grind from a BB by Richard Binder - setup to write very wet with the nib thinned slightly to give just a touch of flex. It is a lovely nib to just doodle with.
The scan of the writing sample below doesn't do this ink justice. In real life it is a beautiful emerald colour with red sheen outlines, lovely shading, and a gold fleck overlay. This ink is the best sparkily ink I own no question.
