Pen works excellently. I received this and two J. Herbin glass pens. This one is far and away better. I wrote a letter with it, and I could write several lines before I needed to re-ink the pen. The Herbin pens ran dry in half the time or less, pouring out ink in the beginning, making me have to turn the pen constantly and scratch out the rest of the ink. The Rohrer & Klingner glass pen released ink at a nice, steady pace.
