These silicone lids by Pratico are a life safer! This past weekend when we had a cookout for our July 4th celebration, our garage was full of flies! I hate flies!!! I was able to use these fantastic lids to cover some dishes for which I didn’t have a lid. They provide a wonderful seal, preventing bugs and such from getting in. I even used the small one as a sink stopper to soak some corn before grilling. My sink stopper is old and probably needs replaced, so it won’t hold water. I just placed the small lid over the drain and filled the sink. It worked very well! These lids are silicone, you can use them on a hot dish or a cold dish, and not have any worries of warping or melting. They have a great grip to them, so you could even use them as a jar gripper! Very versatile! I will definitely be using these a lot 🙂 I received this product for free in exchange for an honest review and all opinions are my own.
