You saw it here first, ladies.
I am not making this up
A friend of mine is currently on holiday in Spain and they sell this at her local supermarket.
I have, obviously, asked her to stock up on my behalf, because I don't quite think I can bring myself ever to use anything else ever again.
Not an AIBU at all, but couldn't think of a faster way to bring this momentous discover to the general attention of mumsnet-at-large.
No need to thank me.
