Hard Fish Pills look just like regular Fish Pills but they are made from hard compressed, molded, durable foam. They have a hole for threading on your line above your hook. Just like a corky but without the hard plastic shell and half the price. Great for adding floatation and attraction to your bait, with yarn or as extra color and flotation for your Steelhead Worm. Guide tested and proven to be successful in catching salmon, steelhead, trout and many other gamefish.
