Wow....Extra Fine means Extra Fine!

I was given the TWSBI Diamond 580 as a gift and fell in love. The pen had a Fine nib, which again, I love but I am addicted to the finest nib I can fine so I had to have the TWSBI Extra Fine just to see....and it is wonderful! It was easy to change the nibs out, it only took seconds to be writing with a nib fine enough to fill in the smallest of forms in style.

EF but smoooth

The TWSBI nibs are such smooth writers for steel nibs, and this EF is no exception. I ordered it to swap for the F nib that came with my 580 (an amazing pen--probably the best deal you'll find) and have not regretted it.
