If you love a little line variation in your writing, or just want to have some fun with a new nib, the FLEX is a great option to consider. Designed to provide some pliability at the nib’s point, pressure applied when writing will create variations in ink flow and, ultimately, your handwriting. This is great for those who want a bit of a calligraphic look to their writing or who generally write in a more Italic/cursive print.
