This bowl works with just about any shaving soap out there, being 4 inches diameter inside. These also work brilliantly with cream, and if you have a good brush, there's really no limit to the amount of lather you can get. The great thing is that this is very easy to clean up and, with just a little bit of wiping down, it restores to its beautiful finish. The bowl comes with a stainless steel lid, which is great for cleanliness and for keeping dirt and debris out of your shave soap.
