Proraso Shaving Soap Bowl is traditionally made in such way that the soap gets to mature in the cooking vessel for 10 days after boiling it and that gives the soap a more concentrated texture. The soap contains glycerin beacause it helps the razor to get better glide and reduces the risk of skin irritations, eucalyptusoil and menthol which have an refreshing affect. This soap should be used together with a shavingbrush.
