Korum Xpert Semi Fix Beads, Tapered to allow a slow release to go from fixed to running as the fish takes the bait. Two colours per pack. 5 x green and 5 x brown to blend in with different lake and riverbeds. Takes a size 10 or 8 swivel. Semi-fix the likes of a Korum Dura-Method or Grub feeder for a neat in-line setup. Semi-fix the swivels from Korum leads and large-eye feeders for a bolt effect.
