Five sizes available: 11 cm, 13 cm, 15 cm, 17 cm, 19 cm. Each size includes four pieces (total 20 floats). Durable buoyant floats designed for saltwater and freshwater use. Stable buoyancy and visibility help keep bait at the desired depth and improve bite detection in varying light. Suitable for coastal, rock, ice, stream and lake fishing; works with a wide range of rigs and weights. Easy to attach and remove with standard bobber stops and slide rigs; compatible with most rods and lines. Built to last in wet conditions, resistant to wear and corrosion. Usage scenarios Coastal or rock fishing in surf: choose the size that matches your rig to keep bait near structure and improve casting control. Ice fishing: large floats above the hole provide a clear bite indicator. Stream and lake fishing: use in windy or current conditions to maintain depth and improve visibility for takes.
