I am thinking of getting a few shave sticks (due to space restrictions, they take less space than a soap bowl...), and it should be a tallow based soap. Which shave sticks do contain tallow (actually tallowate of either sodium or potassium to be correct)? I have heard that Valobra sticks and Tabac stick do contain tallow, but what other brands do so as well, like Speick, Arko, Lea etc.
