One part rocket scientist, and two parts supermodel, the GIR Lid Series turns any bowl into a storage container by making an airtight seal. An alternative to plastic wrap and foil, these lids are made from heavy-duty silicone heat resistant to 550 F. Reheat or steam food in the microwave/stove or bake with them in the oven. Aesthetically gorgeous, and totally functional. Freezer, fridge, and dishwasher safe.
