Brause B66 Writing Nibs - Highly Elastic / Arrow nib is one of our most popular nibs, and is loved by calligraphers everywhere for it's flexibility, impressive strength, and amazing line variation. From tiny hairlines to juicy downstrokes, this nib does it all. The Brause EF 66 also does not catch as easily as most extra-fine nibs, so it makes a great choice for lettering on textured paper. Sometimes referred to as "the Arrow" due to its unique shape.
