I wasn't too impressed with these, I thought they would be more diverse and able to fit different size containers. Unfortunately they are pretty stiff and I had a tough time using them on various things. I think we use plastic wrap beause it's easier than digging out the right size lid for our containers... this puts you right back in the same situation. I would rather just stick to the lids I have, or just using plastic wrap instead and pulling all of these out and struggling with them.
They are also kind of ackward to clean and dry properly.
