All natural, mild heavy oil, manufactured thru a special heat process, it is not rank or skunky in odor. Blends well with almost all oils in lure and bait formulations. It can be used as a base foundation, or as an all-weather or waterproof ingredient. Try it on canines and be impressed. If placed on a dry stick and allowed to soak in, it’s like candy and they will chew up the stick.
