If you have a Bath and Body Works, they sell CO Bigelow which is made by Proraso. You will find it in a tube. A "dollop" about the size of an almond is about right for a nice bowl of lather...
Otherwise I highly recommend you get a tub of Proraso from
The Finest In Gentlemens Shaving And Grooming Needs Their prices are as good as they get and the customer service is unequaled.
Proraso is not the best shave soap in the world, but it is a great soap to base all the others off of & it's quite affordable. Best part about it is that it seems to work in about every water type I have experienced...this is a major plus.
