I picked up a NOS Yardley shaving soap and bowl last week still in the wrapper, unfortunately the tallow or some other ingredient had leaked into the bowl and the smell of the wood had crossed over into the soap.
Result = one musty soap, so in the bin it went.
Maybe it had been stored in a damp environment and thats why it went off.
I'm only posting this as a bit of a warning, as I know there is one for sale at the moment, hopefully though it wont be like the one I purchased.
