Update on the brush nib durability of the Faber-Castell Pitt Big Brush Artist Pens

After using a Faber Castell Pitt Big Brush Black Artist Pen for a couple of hours to draw large sketches on an easel for a Manga sketching workshop, the brush nib tip frayed a bit. Thus it seemed like a good opportunity to test if the regular Pitt nib flipping trick would also work on the large format pens.
The unpleasant surprise was that once the frayed brush nib was removed, the other end turned out to be blunt (no fresh sharp tip waiting on the other end like with the regular Pitt Artist pens). Thus the nib flipping trick does not work with the Big Brush Artist Pens :(.
Took this comparison close-up shot of a fresh nib next to the frayed one before re-inserting it back into its barrel.
The good news is that even with the frayed tip, the pen still works reasonably well with just a faint thin line that might pop up from time to time depending on the angle that the pen is held.
So be extra careful when handling your brand new Pitt Big Brush Artist Pens if you want to maximize the useful life of the fine point of the brush nib.
