The Legend Popping Corks - The Legend Glow in the Dark is designed for night fishing and features the internal sound of The Legend popping cork. Featuring a unique material that can be charged very quickly, shining a bright light (or even a phone flashlight) on the cork for five seconds will make it glow very brightly for five minutes. Recharging this cork with a light source before each cast will help maintain a very bright, highly visible glow. Leaving the glow in the dark popping cork in direct sunlight for extended periods of time can darken the plastic, reducing the maximum glow potential. Store out of sunlight when not in use.
