I-Balz are unique barbell eyes that realy look good on baitfish flies with larger heads -- like spun deer hair, wool heads, rabbit fur heads, etc. They are a little wider than other kinds of barbell eyes so they really look great with those patterns with larger profile heads. 12 eyes per package.
Here is what Spirit River has to say about their I-Balz:
I-Balz (TM) are machined from brass and use a durable enamel iris color with deep black pupils to achieve their super-realistic imitation of baitfish (chartreuse iris for black and nickel plating, orange for acid-etched gold plating). Our machining is unsurpassed and the plating is fantastic. Spirit River is proud to be know as the leader in quality on all our brass products like these cones. Each Eye is machined on a screw machine one at a time. All are then tumbled to remove many of the machining marks...then we plate them with a high quality finish. We then enamel them in the iris and bake them for a good strong finish. Our process takes longer & yes the quality ACID ETCHED plating costs slightly more...but you should expect the best when you take your precious time & energy to tie your own patterns.
