Not bad for what it is

Top Product, works 100%

The suction is great making sure the food stays fresh. I love these.

So handy - keeps fresh and safe from flies

These are just what I needed to keep my oil paints workable overnight. I have a glass palette and another artist recommended using these. Add a touch of clove oil on a piece of cotton wool next to the paint and pop one of these over the top and my oil paints are still open and workable the next day. Perfect. :-) I expect this would work nicely for food too! :-D
