I have been nearly obsessed with finding a good set of Parker 51 clones. I’ve had several (from Jinhao and Junlai) that have been disappointing. While they had the look and filling mechanism that I wanted, many of them would fail in terms of writing well, or in drying out. What exacerbated these purchases was that they would all come up when searching for a “Hero 601” on Amazon, which is the pen I’d seen reviewed that was often praised.
