Dubbing Brush Stainless Steel Wire on a wooden spool with a unique wire holder. The highest quality untempered stainless steel wire made in USA for your Dubbing Brush needs. The size .006 is ideal for medium to large sized Dubbing Brushes for use on flies #6 through 6/0. I use this wire for all of my Saltwater, Bass, Pike, & Musky Dubbing Brushes. We also offer spools of .003 and .009 Untempered Stainless Steel Dubbing Brush Wire for those of you who prefer to make various sized Brushes: From size 8 down to a size 26 hook we suggest the .003 sized wire. When using Natural Fibers or choosing to add some extra weight for Extra Large Brushes you'll find the .009 size to be the best choice.
