If you’re looking to reduce the amount of disposable plastic, opt to use these silicone lids. These lids wash easily so you can reuse them time and time again. The flexible design clings to different types of containers, whether plastic, metal or glass. The larger size stretches to fit most standard mixing bowls, while the smaller and medium sizes are great for cans, bowls, or cups. With compact profiles they also take less space in the drawer than most standard packaged cling wrap. Hand wash recommended. Great stocking stuffer for the holidays. Please note while the lids are made from silicone and are stretchy, the lids do have a limit to how far they’ll stretch.
