Why we picked it
Both the dish and the lid are Pyrex borosilicate glass, made in France. A removable silicone seal makes it airtight, and with the seal out, the dish and lid can go in the oven.
Best for
Storing and reheating leftovers with glass on every side, including the lid
Not for
Packed lunches where weight matters
