A Wee Scot, in a pill container. The little brush that could.
Not empty quite yet, but I've since taken it out of my travel kit, since I'm going to want to savor what I've got left. He also did a mentholated AS, Frostbite, that also had an optional flask. The flask is honestly a bit awkward while shaving -- a flask is not a container optimized for stability on the side of a sink, it turns out -- but it's definitely a classy touch.
