I thought these coffee cups would be a way for me to keep up with cups mugs and tervis glasses from disappearing. They would be carried out the house each morning--never to return. These are fine for the first 10 minutes...then. SQUISH ! The middle gets very soft. If you put it in your cup holder and reach for it a few miles later--OH DEAR !! It will spill over the top. An OK cup for a small gathering of folks for a taste of tea....
