This silicone lid seals tight on all smooth rims, stainless steel, glass, plastic, melamine. It goes in freezer, microwave, oven and dishwasher.
This handy 8 inch size fits most of the serving bowls I use, but there is also a larger size and smaller ones which fit perfectly over a wine glass while you sitting outside grilling.
It goes on and off easily and saves reusing foil or plastic wrap. It opens very quietly and seals just like the cook left it so no one knows you are snitching a taste!
I found it at Sugarbakers in Omaha. It also comes in different patterns, a sunflower and a poinsettia were also at the store.
It is a really neat little item!
