Most of Decor food storage products are freezer safe. To check if a product is safe for the freezer, look for the below icon on the base of the product:Please note to be careful when handling products when they are frozen. Freezing can cause products to become temporarily stiff, making it difficult to remove their lids. If the product is dropped or knocked straight out of the freezer it could break.Hint: After taking a product from the freezer, we recommend that you allow it to rest at room temperature for a few minutes, or run warm water over it for a few seconds. The lid will then be easy to remove. DO NOT run water over a glass storage container that has been in the freezer.
