Martin de Candre make one of my favourite shaving soaps. You can find details here:
For a 170g jar, at 34 euros it's still an expensive soap. But at long last, they now make a more reasonable shipping charge of 6 euros to the UK. So when my jar is finally used up - it's lasted over 2 years so far in my rotation - I'll be reordering.
