This air fryer egg mold is made of thick silicone material, which is soft and durable, effectively avoiding collapse or warping during use, and is very suitable for long-term use. It is a natural non stick pan that roasts perfectly round and won't stick to the bottom after baking. It is easy to rinse and you can also wash it in the dishwasher. The silicone egg stealing cup measures 4 x 1.3 inches and has enough space to put vegetables, cheese, cooked ham, bacon, and other foods into a container. It is perfect for use in a microwave, oven, refrigerator, or steamer.
