The product is a pack of 20 plain brass Colorado spinner blades in gold size 4. These spinnerbait blades are designed for freshwater fishing and are suitable for targeting a variety of fish species such as trout, salmon, perch, chub, bream, pike, walleye, and bass. Made of brass material, they have a neutral buoyancy and weigh .14 oz. per blade. These blades can be used to create custom spinnerbaits for a tailored fishing experience. They are new but they were in a tackle box so they collided with each other and got a few knicks on them, but they will still work.
