This Special is a combi purchase of a salt grinder and a salt refill box. All grinders are refillable and for that reason we like to 'cover' you with five extra re-fills. Clean the grinder top once a while with your daily dish wash routine and re-fill your grinder on time. In this way, your grinder will run for 2 till 3 years The labels are protected against oil, acid, etc. They will keep their color and brilliance.
