I have to travel a lot and sometimes overseas and have found shave soap to be easier to use and less messy than shave cream. I have a Col. Conk travel soap container and have noticed that many containers barely have room left when the soap is in it. After using it, (I carefully swirl the brush about 20 times) there is still moisture on the soap and around it. Is it okay to just screw the lid back on and throw it in my bag, or will then build of moisture everytime I use it decompose it somehow? I also have the same question concerning the Proraso tub soap.
