Review on Longzon Silicone Stretch Lids 14 Pack - Reusable Food Storage Covers for Bowls - Dishwasher & Freezer Safe - 7 Different Sizes - Including 2 XXL Sizes up to 9.8'' Diameter by Robert Mac

I am very disappointed in you. They don't stick to anything unless it's the exact size of the item. I have square cereal bowls with rounded edges that go up to size 6 before they even fit on the bowl. Even then it isn't "sealed", the next number down doesn't stay over the bowl and roll/slip back, and neither is a seal. Light enough to clean in the dishwasher but not in a promising commercial condition at all. I travel a lot so my returns window closed before I could try them at home and am now throwing them away. They don't have sizes that even fit in a real bowl or larger.
