Tronixpro beads come in a range of colours and sizes. Smaller sizes make excellent stops between the crimp and snood swivel on a rig body. Larger sizes are suitable not only for attraction but for buffer beads, especially when boat fishing to put between a Tronixpro Zip Slider or Ledger boom and the swivel or link. All beads are made from quality shatterproof polycarbonate.
