My mother recently unearthed my great grandfather's shaving mug and gave it to me after cleaning it up a bit. It's a beautiful glass piece that's just a little over three inches wide. What's interesting is that it has five curved feet (of a sort) in the base that form a circle. I started using it with a 3" wide puck of soap that sits on top of the feet, but I can't help thinking that they're actually designed to hold soap in place rather than elevate it. They seem to be just the right size to hold a puck of vintage Williams or Colgate. All of this brings me to the following question: Are there any modern soaps made in that size? I'd like to grab something high quality and take this thing for a spin the way it was intended!
