Drawing straight lines is the basic element in art, but it is also something that may take years of practice. Even then, smooth lines are hard to perfect. This is what everyone struggles with.
This is why a self-correcting pen that smoothens out your squiggly line was designed.
The PROLINE pen is equipped with an innovative free-rotating nib bundle designed to enhance the fluidity of your lines, resulting in smoother sketches. Developed specifically for designers, PROLINE elevates sketch quality and presentation standards with minimal effort.
