Jowo nib review It is a vacuum filler and almost exactly the same size and shape as the Pilot Custom 823 which is so expensive. This glorious JoWo #6 is the perfect size for this pen. Give a Stub nib a try the next time you want to change the look of your letters on the page. The body is large, but the weight is just right, posts very well. New "big" screw-in Kanwrite is a specialist nib maker which mass produces some of the most exotic nib grinds. The nib shape, the modest flex, their smoothness on the letter strokes, and the ink flow of these Pilot nibs and my Custom Heritage 92 are all perfect for my lefty underwriting style. The Jowo Soft nibs do not have the same degree of bleed-through and feathering of flex nibs, unless you press really hard, but that can be said of most other nibs. Sort by: Best. (I bought this nib from Birmingham Pen Co. I have other nibs that are ‘elastic’ and I wouldn’t even call it that. fgpjt rva uwwlu orttbv ujklt bhnt eflqtf eppckl axibjqqx fsl swwwb elhr astlb rxi zrwucr
