Esterbrook J-model pens are fun to collect for all of the dozens of nibs the company sold. Overall, this is a standard black J-model. Remarkably, it still has a functional Esterbrook imprinted ink sac. More impressive is that it comes with an upgraded 2284 steel nib. This was intended as a "Signature Stub" nib. It has some gentle oblique and stub qualities, but, overall, it writes more like a double-broad nib. Take it easy on some corners, as it can dig in a little. However, the nib can be extremely smooth when you get it angled correctly. The cap and barrel have some wear from use but no cracks. 12.8cm capped.
