The bowl is perfect for first time feeding and food storage. The lid of the bowl can be used as a plate and also inserts into the bowl creating an air tight seal for storage. Simply press the middle of the lid to create an air tight seal pushing out any excess air. By removing the air from the bowl, food stays fresh longer! The silicone bowl is 100% food grade silicone with an embedded stainless steel ring to hold its shape. It won't collapse when gripped. It's also MICROWAVE SAFE. That's right! You can defrost and warm up food in the Silibowl. The perfect alternative to plastic bowls!
