From Esterbrook:
The “J” was the original Esterbrook’s sleek and suave, classic 1940’s and 50’s pocket pen that appealed to the practicality of the times. It was the perfect pen for both men and women, and we think it still is today. Our new “JR” model, introduced as part of our revival of the Esterbrook brand and added to our core line of collections, is stylish and refined without being too fancy. It’s meant to match your style, as nicely as it graces your hand. With an elegant design, that isn’t fussy, it is compact in size, so you can always have one on hand and with you on the go, wherever you go.
Both the German JoWo nib and the top of the pen have been engraved with the Esterbrook Eternity symbol.
