The OMC Vitabitz Anti Tangle Sleeves from One More Cast are a simple but essential part of any rig setup. They sit at the core of the rig, often overlooked, but they play a key role in preventing tangles and helping the rig reset after nuisance fish have disturbed the hook. The sleeves fit perfectly over all size 8 swivel types. - Pack of 10 - Sizes: 30mm or 50mm
