Osprey Pens introduces Jowo compatible special grind nibs: Size 6 Steel Zoom BB a.k.a Zoom Double Broad

With a Zoom nib, line variations depend on the angle at which it is held, low angle gives thick lines, high angle (almost perpendicular to the paper) produces fine or thin lines. Good nib for sketching as it generally writes wet, especially for someone that likes medium to broad strokes. Flipping the nib to get thinner lines is always fun! From changing the angles from 15 to 45 to 90, you can get thick to medium to fine lines, which means you can almost get 3 different nib point writings with this one nib!!

 These Nib Unit works with pre-filled ink cartridges or with bottled ink using a  generic international converter
