I've only used Proraso Green soap, which comes in a nifty little container with a snap on lid...great for use, storage, and portability. I've seen Williams soap at the store in a box. What are you supposed to store it in, if anything, and where do you put it when you are loading your brush? Is this how most soaps come, or do they, like Proraso, come in a container that facilitates ease of use? What's the deal with sticks? How do you build and apply lather? Is it better to get creams in a tube or tub?
