The choice is yours, whether you grind salt or pepper, the BODUM Twin duo grinder serves both purposes: made of stainless steel, santoprene and acrylic it fits perfectly in every hand. The colours of the different parts hint at their specific function: The black base indicates the pepper compartment, whereas the partition with the white base is reserved for salt. Adapting the Twin duo grinder to either salt or pepper grinding is done through turning the santoprene grip to the left (salt) or to the right (pepper). The cleverly devised Twin duo grinder makes life easier for those who like to have a multi-functional design solution!
