These are fantastic, very easy to open and close. I have problems with my hands and find it quite difficult to get lids off other containers and usually end up with cereal, spaghetti etc all over the place, or I have to wait for someone to help me open the container, but with these, I do not need to wait for help and there is no longer a mess. I can open easily, just one simple push on the lid opens and closes them. I highly recommend them.
