Our Bearing/Linkage Oil (BLO) is a tremendous product. Users tell us that when they use BLO they have feelings of euphoria that can't be duplicated with anything else. BLO can be used almost anywhere, but generally players use BLO while they're lubricating all of the bearings and linkages that commonly exist on brass instruments. BLO has a unique precision tip with a cover that prevents leaking and breaking–so no more having to put your BLO in a plastic bag! When your BLO is depleted, simply call up your local dealer and ask them for the best BLO they can get their hands on.
