I just inked up a nice Hero 7022 with a nice purple ink. The nib is a medium fine and the ink flows nice901.The 7022 is a nice weight, heavier and slightly thicker than the Hero 221, yet lighter and slimer than the Hero 901. The 7022 is a good compromise between the 221 and the 901. The ink flow is almost as bold as the 901 and the nib writes and draws smoothly across the page. It has a piston fill converter included and will accept cartridges. However I haven’t tried using them.
I am pleased that I bought two of these pens for gifts. They are a lovely red and gold solid metal bodied pen. The cap is tight fitting and posts securely. Overall a very nice fountain pen.
Cheers on this chilly evening, james
