The combination of pigment and new colour material provides black density about twice that of conventional ink.Newly-developed JETSTREAM ink features a low viscosity, highly lubricating solvent not used in conventional ball-point pens. By reducing the coefficient of friction, this assures an incredibly smooth feel when writing.The high viscosity of conventional oil-based ink (right) results in a comparatively heavy feel when writing. With the newly developed ink (left), you can enjoy an exceptionally light feel.
