The Tronixpro Round Beads Max Pack contains 4mm beads, a small to medium-sized rig component used mainly for attraction and for securing other parts of a sea fishing rig. At 4mm they give a neat, streamlined rig profile while still offering enough visual presence to draw attention near the bait. The Max Pack format means a significantly greater quantity than the small retail packs. Standard smaller packs of 4mm beads are also commonly sold, and 4mm beads sometimes form part of the larger coloured Max Pack options. - Size: 4mm diameter - Quantity (Max Pack): significantly greater than small retail packs; exact count may vary at this intermediate size - Material: durable, shatterproof polycarbonate plastic - Colours: Luminous, Clear, Black, Red, Yellow, Green, Orange, and Mixed packs Common uses for 4mm beads: - Snood stops (rig body): crimped in place, often with a small crimp either side of a swivel, to create a fixed position for a snood. Small enough to stay neat, large enough to secure most common rig swivels. - Attraction: coloured or luminous beads fished on the snood near the bait provide visual attraction, targeting species that respond to colour such as flatfish. - Buffer: a light-duty buffer protecting the knot on a swivel from the hard edges of a crimp or other metal component. - Continental rigs: a good size for building neat, slightly heavier Continental-style rigs where a delicate presentation matters less than on ultra-fine rigs.
