Pivot beads where the start of the cascade type rigs. Some clips have a bait clip on so can be relayed, all clips have a line store to take up slack so the snood can fit snugly into the clip below. The line store can also allow for a hook change. Although these have been superceded by the cascade swivel i find them useful for night time fishing and for larger baits as not as fiddle as the cascade swivel. 8 per packet.
