Features: These containers boast crystal-clear, heat-resistant borosilicate glass that resists stains and withstands everyday use. The thickened glass is transparent, allowing you to easily identify contents, while the food-grade bamboo lids offer a warm, natural aesthetic to your kitchen. Each lid is complemented by a sealing silicone ring to prevent spills and leaks, providing you peace of mind. Ideal for cooking, baking, and storing, these containers transition seamlessly from refrigerator to oven. Withstanding temperatures from -4? to 752?, these glass bowls make meal prep a breeze. The bamboo lids can double as cutting boards, perfect for slicing cheese, fruits, or vegetables—not only stylish but practical too. For the best sealing performance, allow hot food and containers to cool before placing the bamboo lids. If the lid does not fit tightly immediately after storing hot food, this is a normal result of thermal expansion and contraction and does not affect the product's quality or functionality.
