Breton French Grey Bath Salt is a bath salt harvested by hand in the Gu??rande region of France. This all-natural sea salt is gathered using ancient Celtic methods that preserve the inherent mineral content of the salt, using all wooden tools. Breton undergoes no treatment, washing or refining after it is harvested from the clay-lined ponds that give it the treasured grey color. Prized for its high trace mineral content and moisture, this French sea salt is world-renowned for its traditional harvesting methods and beauty. Ideal for a luxurious bathing experience, Breton can be used for soaking in the bath or in your own bath salt creations.
