I just got a rather unique shaving mug. It is a Marvy unbreakable mug. What makes it unique is that it will accept the larger soap pucks as well as smaller ones. The small pucks fit nice and snug because the mug has a built in smaller ring in the bottom to hold the smaller pucks in place instead of them sliding all around. Just seemed like a good idea to me. Because it cost less than $12.00 it's a good buy also.
