Savinelli Arcobaleno Red Smooth Pipes are some of their most eye-catching briars. The smooth finish is treated with a vivid red stain, which is a beautiful contrast to the brilliant black acrylic stems that accept the popular Savinelli 6mm balsa filter. For those who don't like to use a filter, and adapter is included that allows you to keep the airway at a consistent 3mm. A silvertone trim ring separates the stem from the stummel, and is raised above the surface of the shank. Besides being incredibly handsome, these are some of the most affordable smooth-finished pipes that Savinelli makes.
