The shape of the Twin has been ergonomically designed by Bodum to make using the grinder as comfortable as possible. The grinder is round at the top and elliptical at the bottom, making it more space-saving. Practical and space-saving: the Twin salt and pepper mill holds both salt and pepper at the same time. By turning the lid, either salt or pepper can be ground: a right turn for pepper and a left turn for salt. The powerful ceramic grinding mechanism is adjustable from fine to coarse. The transparent outer walls allow you to see at a glance how much of the contents are left. The silicone strip ensures a stable and secure grip while handling.
