Love having these when I don’t want to transfer food to another container just to put in the fridge. So handy!! Also they work great to slip on a 1/2 of a watermelon, cantaloupe or other round food item!! Perfect on pet food and paint cans. Being dishwasher is also perfect.I had to send these back. They did not stretch over bowls like they sad they did.Don’t buy it! waste of money because they don’t even stretch. The lid keeps falling off and snap back and spill the food everywhere.convenient and easy to useGreat addition to any kitchen! Have used on bowls of pasta and did not stain. I've seen other lids, and they just don't seem to be as nice and clean looking as these ones! Great product invention!!Awesome product! Saves doing unnecessary dishes and washing Tupperware which I hate!!!Love it! Easy to use, easy to clean.Very handy in the kitchen. Turns bowls and dishes into airtight food savers!
