The OXO Angled Measuring Cup Set is really convenient to use because they do not take up too much space like other measuring cups that are used to measure liquids. They are able to stack inside one another. They are also clear to read the measurements on the side of the measuring cups. You don't have to struggle to read the numbers. These are also really easy to keep clean, since I just put them in the top shelf of my dishwasher. This always gets them clean, and I don't have to worry about them breaking or cracking at all since they are sturdy. Ease of Cleaning These are very easy to clean because I just put them in my dishwasher. Durability I keep these all stacked within each other in one of my cabinets. They seem to be durable since I never had a problem with them breaking or cracking when they hit against other items in the cabinet. Design I like that these are designed to stack inside each other. This is a great feature because it really helps to save space.
