The timeless Peugeot Paris salt mill boasts a Zirlion grinding mechanism with U-select, allowing for a seamless adjustment of the grind level from fine powder to coarse grains. You can customize the grind by turning the ring at the base. The Zirlion mechanism is made from zirconium, a material commonly used in demanding industries such as healthcare, cosmetics, automotive, and aerospace. Zirconium is highly resistant to corrosion and offers exceptional hardness, outperforming conventional ceramic or steel. Peugeot backs the salt mill's grinding mechanism with a lifetime guarantee. The exterior can be cleaned with a damp cloth.
