This stainless-steel Prepara bottle stopper adds drip, drizzle and pour settings to most standard oil or vinegar bottles. Simply twist the spout to your preferred pouring speed when you're mixing vinegar into a recipe, transferring olive oil to a measuring cup, adding a finishing touch to bruschetta or dressing a salad. This drip-free pourer has a sleek modern look and creates an airtight seal when not in use.
