Heating in an oven or microwave oven is OK Silicone is heat-resistant and can handle temperatures up to 210°C, so it can be heated in an oven or microwave. In addition, it is BPA-free, so you don't have to worry about harmful substances transferring to the food even if you heat it, so it's safe and secure! 2. Excellent durability and can be frozen Silicone is highly durable and resistant to low temperatures, so it can be stored in the freezer as is. Because it is a soft material, it will not crack or deform even if it is thawed, and it can be used for a long time. The sealed lid prevents the contents from leaking, preventing frost and freezer burn! 3.
