Sold as Individual pieces.  

These are replacement / extra base rings for our metal ferrules.  

These base rings are available in a variety of colors and in two sizes (0.3" and 0.1"). The rings fit into the base of the metal ferrules and can be turned down upon installation to make the metal ferrule to sit perfectly flush on the hosel like a traditional plastic ferrule.  We also offer plastic spacers that fit underneath the metal ferrule with no visible plastic base ring but the quality of fit of the ferrule depends on the diameter of the hosel of your irons.
