I don't remember where I bought this soap puck. It's from a boutique soap maker in Barcelona, Spain. IIRC, I added it to an order when I needed to spend a few bucks to get free shipping. I grated the puck into a container, wet it and shook it vigorously yesterday. Today I lathered a badger brush for a headshave with it and I'm amazed. It provided a very good shave. The base ingredient is olive oil.
