Esterbrook pens are one of the century's best design feats. They're well-built but inexpensive, and they last better than most pens. They almost define the term "under-appreciated". The mother-of-pearl look in a variety of colors is really pretty. The pens write well, and if you don't like a nib but you love the look of the pen, the nibs are interchangeable (Renew Points). Almost all are steel, but there are gradations. The 9xxx series with their "Durium" tip is the best. I have quite a few Renew Point Nibs if the choice you want isn't on the pen, including some stub nibs. Most of these Esterbrooks were made between the late '40s and late 1950s.
