The Esterbrook fountain pen, is a fantastic work horse in the world of fountain pens. They are simple, durable and write very well. They have replaceable nibs and have stood the test of time.
I recently acquired a few Esterbrooks. They are inexpensive and fantastic vintage writers. I have an J, LJ, SJ. Its very lovely, I have it inked up at the moment with Diamine Pumpkin. A nice festive orange perfect for the holidays. I will be writing a review of some of the Estys in my collection in the coming weeks.
