Patented silicone seal with 2 unique air vents allows you to keep the lid closed, and keeps moisture inside while baking, steaming, or microwaving. All the nutrients and great flavors remain in the food.
The bowl is perfect for my need to keep a food item hot at the table while the rest of the meal is being brought out. The lid fits securely and the handle grips have a slight separation so it makes it easy to take the lid off. If they make a larger one, I'll buy that too. This bowl only holds enough for two....maybe three.... Jo. Goodyear, AZ. Sat Aug 03 2019
