4. Will peppercorns and rock salt fit through these? Thanks!
Answer: I haven't tried pouring the items you specified. I think the peppercorns would fit if poured slowly. I'm not sere about rock salt- depends on the size of the granules you use. I think most would pour through the funnel. Nice space saving funnels.
