These are really useful and relatively easy to use. I use them a lot. The material is stretchy but sturdy and sticks to the metal or glass container pretty well. If it's tight enough you can even create a little vacuum seal. Most important part is that it's plastic saver and saves the enviorment!
These silicone stretch lids stretch and fit tight on any container. I love the variety of the lid sizes and they perform very well. It's very useful in storing food. Since I've bought it I use it a lot. I'm so glad I purchased this
We’re ditching plastic at home. These silicone lids are great to keep food fresh, easy to clean and totally reusable, brilliant product!
