I love Proraso tube cream, the green and the blue.
I soak my brush in hot water ,squeeze the excess water out, then add an amount of cream to the tip of the brush and start working it in a bowl with a few drops of water. After a min of mixing ill add a few more drops of water and repeat until i get a really rich lather and the more you mix the better the lather.
I think one of the best Proraso items is the afterburn lotion .It has alcohol in it but the smell of that stuff is unbeatable imo..
