Rod Twis-Bar - ArtDriver -

Torsion bar Twis-Bar exclusive of Artdriver.

Its system of spiral cuts (exclusive) allows the bar to contract on its own axis, which at the same time has a self-push towards its original shape. This allows you to work with better and more smoothness when shading, color and lines. Fully certified and tested by the best artists.

It is recommended to use with the ZeroG pulley.

Patented model.
