Anyone know any good travel tubes for shaving brushes? I already own the Muehle one http://www.westcoastshaving.com/Muhle-Ro..._2533.html. I've seen some interesting ones form Simpson http://www.simpsonshavingbrushes.com/cgi...rod_CASESL, shaving-shack http://www.shaving-shack.com/shaving-bru...-tube.html, and this one http://www.amazon.co.uk/Large-shaving-br...B008YEPZ68.
