The beauty of the Pyrex 4 Cup Measuring Lid lies in its versatility. Not only does it serve its primary function of measuring ingredients, but it also transitions seamlessly into a storage solution. Use it for meal prep by measuring out portions of ingredients ahead of time; the lid ensures everything stays fresh. Additionally, the glass material is microwave, oven, and dishwasher safe, adding to its versatility and convenience. You can microwave soups and sauces directly in the measuring cup, then store leftovers with the lid, all in one vessel.
