Axys Rotary Valhalla Pen (25mm Grip)

This isn’t just another pen with a spinning grip.  You not only adjust needle protrusion with the Valhalla’s grip, but the stroke options allow you to choose your hit.  Whatever you need to do: lining, packing, coloring, blending, shading, its all there at your fingertips, 5 strokes in 1.
