Review (5/5): I tested this as a pre-shave oil, and it proved superior
I use this as a pre-shave oil. It's not the first one I've ever used. I received some as a sample, and as an experiment, I used my traditional pre-shave oil on one side of my face and the Jack Black oil on the other side of my face. I got a much closer shave with the Jack Black side, so I switched, and I've been using this ever since.
