These silicone cupcake liners are crafted from food grade silicone, ensuring safe contact with all types of food for daily use. They boast an impressive temperature resistance range from -100 degrees Fahrenheit to 446 degrees Fahrenheit, making them fully compatible with microwaves, ovens, refrigerators, and dishwashers. This versatility allows you to use them for baking, heating, storing, and cleaning with maximum convenience, eliminating the hassle of switching between different kitchen tools. Coming in three practical shapes round, square, and rectangular these liners double as effective lunch box dividers. You can mix and match them based on the size of your lunch box and the type of food you're packing, creating separate compartments that prevent flavor blending and keep your meals organized. Unlike thinner alternatives, these liners are designed to be thicker and sturdier while maintaining a flexible texture. This unique combination ensures they retain their shape even when filled with food or cake batter, standing firmly on baking sheets or inside lunch boxes without tilting or shifting, providing reliable support for all your cooking and packing needs. As reusable muffin cups, they can be used thousands of times, offering a cost-effective alternative to disposable paper cups that also reduces environmental waste. Color: Neutral.
