Just the right amount every time - the stainless steel spout has a steady even flow that pours just the right amount of oil or vinegar where you want it when you want it. The silicon plunger cap fits tightly to the bottle to prevent spills or leaks. So many uses - using it for cooking oils or for balsamic vinegar are the most common uses. Here are a few other uses: soy sauce, Worcestershire sauce, homemade salad vinaigrette, wine, water, liquid soap, and mouth wash. Save money - if you are constantly buying olive oil, purchasing in bulk can help to save up to 50% at warehouse stores. Refill the bottle every few weeks from the bulk container.
