A UNIQUE writing tool like you have never seen before, perfect for easy and expressive writing or drawing. The modern shape of the body and the translucent grip end with a special tip.

​

In conventional rollers, the metal ball is supported in a metal "sheath", and the ash flows on the edges of the ball. On the AIR roller, the ball is caught in a "plastic acetate" sheath that ensures less friction with the surface of the paper at any writing angle while allowing the ball to rotate.

​

When the roller is pressed on the paper the ink can flow freely, allowing to obtain thick ink lines, similar to a pen, when the pressure on the roller is small the ink flows only on the edges of the ball.
