Ruling Pen, Acurit The Acurit Ruling Pen is a useful tool for creating spectacular designs and bold calligraphy. The pen works well with traditional and acrylic inks, liquid watercolors, fluid acrylics, and other liquid media. Instead of spending money on multiple sizes of script and liner brushes, you can use this one ruling pen to create a variety of line widths. Fill the pen reservoir by dipping or drop a small amount of ink between the two metal blades using a brush.
