Because it's rubber-coated, it prevents line breaks by not damaging the line. Due to the rubber coating, it doesn't pinch the line with lead, preventing damage. Also, it can be used repeatedly, and unlike lead-only split shot, the rubber processing makes it less likely to crack when opening and closing, allowing for repeated use. It's reusable, making for good running costs and long life. You can enjoy stress-free fishing because the split shot is less likely to slip when setting the hook. Size: B Quantity: 30 pieces
