CorQs STRIKE INDICATORS are among the very best that we've ever tested. They're built with lightweight, premium cork - they land super-soft and float super-high, PLUS minimize surface friction/disturbance when re-casting. A rubberized O-ring keeps the indicator from sliding down the line, even on light tippets (6x, 7x, etc), yet are easily adjustable for different water depths. And that same rubber loop will never cut or nick your line. The porous surface texture displaces water quickly with less effort, allowing you to pick-up subtle strikes that would otherwise go undetected. ECO-FRIENDLY: They look more natural to the fish, because they are. MADE IN USA. SIZES: 1/2", 5/8" or 3/4". COLORS: (1)Natural, (2)White, (3)Neon-Assortment, (4)Red, (5)Black. 3-pak
