This flex nib is a very high quality, beautiful fountain pen, it lies very well in the hand. This allows you to write very fine lines, and with a little more pressure, you can also write wider lines. With this fountain pen the handwriting is much better, no comparison to other nibs. I hadn't done calligraphy before, it's so much fun with this Pen that you want to write over and over again. I had a few questions about the Pen and I can say that the support is excellent.
Highly recommended!
