A traditional manufacturing certification
Le Sérail received a distinctive mark awarded by the CCI de Marseille, certifying its authentic craftsmanship. This distinction demonstrates respect for the traditional methods of Master soap makers, with saponification in a cauldron. Le Sérail is among the last to perpetuate this ancestral process for the manufacture of real Marseille soap.
If you’re looking for authentic Marseille soap, Le Sérail is the place to be. Choosing Le Sérail soap means choosing artisanal expertise that has been preserved for generations.
