Floppy not rigid, but they do make a very tight seal
Reviewed in the United States on April 13, 2019
From the pictures I expected firm but stretchy lids. These are more like thick floppy rubber...almost like balloon rubber but much thicker. At first I was disappointed as I expected them to replace, and be somewhat similar to, the lids that came with my Pyrex and Anchor Hocking bowls. They are more like plastic wrap on steroids. So, in the end, though not as expected, they are pretty useful for covering bowls with a really air-tight seal, and, unlike firm lids they stretch to fit perfectly over many different size bowls.
