Now, for the first time ever, you can adjust the buoyancy of your float! First, attach a Rod-N-Bobbs Mr. Summer Foam Bobber Float to your fishing line and drop it in the water. Next, simply cut or tear excess foam riding above the water line and add a Vis-Stick (included) or Lightstick, and youre all set! Save excess foam for later use. This is the first time buoyancy can be taken away and removed from the water, eliminating excess resistance and allowing you to catch more fish. Per 4. Sizes: 3, 4, 5. Color: Yellow.
