    This nibs are really magnificent, especially when you have shimmer and/or high shading inks. My favorite nib size by far!

    My first stub nib, and I am loving it. Very smooth and wet on the broad side, crisp on the thin side. Great to be able to switch different nibs in and out in the TWSBI Diamond.

    This is my first stub nib and it did not disappoint. It provides a lovely line variation and I’m happy about this purchase.

    This is a true western EF nib, which is just a hit smaller than the F nib of my TWSBI Diamond. It has a consistent flow with quite a bit feedback during writing, If paired with wet inks it will lay down lovely wet fine line. Overall I am satisfied with this purchase!

    I ordered this replacement nib because I wanted a 1.1 nib on my favorite fountain pen (580 Diamond). As with the last Nib, the change is very fast and easy.

    The quality is great as always and the shipping was fast.

    The change is fast and easy. And by the way: this could be as easy way, to get different nibs on the 580.
