Food material: Our silicone lid is made of BPA-free, non-toxic, environmentally friendly recycling and 100% pure silicone material. Not a strange smell, safe for your health. The thick covers are durable and not easy to tear or warp. Multi uses: With the 6 different package sizes, you can use the silicone stretch lids to hold almost all crockery items, bowls, cans, jars and containers that can be covered, and even cover your half-cut melon or watermelon with them. Cold and heat resistant: The silicone material is resistant to both low and high temperatures. So put the stretchable food lid in the freezer or even in the microwave and dishwasher. Easy to handle: The lids can be used directly over bowls, glass lids and hot dishes to avoid container transfer. International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
