Tactile Turn machine a groove along the entire length of the pen that is hard to describe. It won't bite into your skin, but it provides just the right amount of grip. It is subtle, but it also protects the pens from light scratches by providing a textured surface that disguises light scratches much better than a smooth surface.Comes with a Schmidt Easy Flow 9000 medium point with black ink and will fit all other "Parker style" refills.
