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.
