Geeez, some of my best and closest straight razor shaves were with canned Barbesol shave cream (or foam - whatever you want to call it). I think both Dollar Tree and .99 Cent Only stores carry Barbesol.

My only gripe with canned shave cream is that you can never get all the product out before the propellant runs out. Otherwise I've found nothing wrong with the canned stuff.

I also prefer to use a mug and brush.
