Olive oil was used by many old timers to lubricate and revitalize their saddles and boots. We bottle our oil that does not pass our stringent taste test for this very purpose. We find that the leather soaks up the oil leaving no residue. The leather is rejuvenated and ready to use for years to come. Our 16 oz. plastic bottle has sufficient oil to treat 4-5 saddles. This product may darken leather.
