Features a stainless steel base and a premium silicone food compartment that can go from refrigerator or freezer to microwave and oven. We've also added colorful soft touch silicone clips for easy opening and closing.

Firmly push the lid down on all sides so there are no gaps then close the clips. + Do not overfill, always leave a minimum gap of 1.5 cm at the top of the insert (if using), or the stainless container.
