For bait finesse that emphasizes spool rotation performance.Ideal for reel spool bearings.100% chemically synthesized oil that does not contain any impurities refined to high purity (the oil itself has not changed from "Super Fine Sluve").Very low frictional resistance for extremely high levels of spool response.Achieves ultra-low viscosity without solvent dilution, no change in viscosity due to solvent volatilization.The container has become a hard type, making it easier to carry.Includes ultra-fine dropper.
