I use it especially for writing titles lessons and notebooks, with red ink (so I opted for an extra large feather). His pen (1 mm) ensures a decent plot. Obviously, it takes a little practice to write well with such a pen but the result is the same!
Having had the opportunity to also test the medium point version, I advise you to avoid opting for a lower pen size (fine and extra fine) because the size M already allows very fine writing.
Highly recommended.
