Each cone is machined on a screw machine one at a time. All are then tumbled to remove many of the machining marks...then they plate them with a high quality finish. The process takes longer and yes it will cost a little more...but you should expect the best when you take your precious time to tie your own flies. These cones are ideal when streamers, sculpins, and deep running minnow patterns require more weight than Brite Beads provide. 20 per package.
