Apparently S'buries dont cater for people who dont want an unnecessary essentially untested new nano scale product in their socks....
It is rather alarming that nano-particles are so much more controlled in my work environment than in for instance sainsburys....
I am reminded of a previous product that was cheap fantastic and funky and went into everything from concrete through wallpaper to ironing boards before the health implications had been properly examined, and which people now have to pay $$$ to get removed from buildings by people in HAZMAT suits....
