The J series was introduced by Esterbrook around 1943 and was an immediate success. Despite being a relatively inexpensive pen, they are incredibly well made. The use of thicker walled plastics prevented any distortion and the extensive use of stainless steel for the trim ensured that the pens last for years. All the nibs were made from high quality stainless steel and Esterbrook took the innovative step of making every nib fit every pen by using a standard threaded mounting system. It is rare to find a distorted or corroded Esterbrook even 70 years after they first appeared and this is a great testament to the company and the fabulous work of its designers.

The classic double jewel J series came in three sizes J (full sized), LJ (slender), and SJ (demi) and in six classic colors. Double jewel models come out around 1948 and were produced in vast quantities, with many showing up with in perfect writing condition.

There were three main variants of the J series;

The Standard J, conventional length and diameter.

The LJ, same length as the J but narrower.

The SJ, same diameter as the LJ but shorter.

All the nibs were interchangeable with any model in all three ranges. There were two grades of nib fitted to the Esterbrooks, the Duro range or the more expensive and better quality Master nib. All the pens were also available in the same range of finishes.

The Esterbrook J series pens are a delight to use and the steel nibs are incredible. They have always been regarded as great writers and are now becoming more difficult to find.
