The Savage Gear Glass Rattle Kit includes 15 calibrated glass beads (5 sizes S, M and L) designed to fit easily into your soft lures. Ideal for producing a clean, even snap, this kit instantly revives the attractiveness of your 3D Trout Rattle Shad or 3D Crayfish, and can just as easily be used to create your own custom rigs. The crystalline sound and vibrations generated stimulate the aggressiveness of predators, whether in fresh or salt water, to trigger reflex attacks. Easy to install, this kit is a must-have for effective pike, zander and black-bass fishing.
