I've one of those grooming kits from the 1930s that was completely unused which contains a still wrapped shaving stick. This thread has reminded me that I need to try it out sometime.
I did the same with a 1Kg brick of P160, I like the soap and it was going out of production also as Pedro said it was cheaper that some were selling 100g for. I just keep mine in a sealed container still smells as good as the day I bought it.........:dodgy::dodgy:
