Duralex Freshbox Glass Bowl

Yes, the tempered glass is designed to withstand microwave heating. However, always remove the plastic lid before placing the bowl in the microwave to prevent warping or damage.

The snap-on lids are designed to be airtight, which is excellent for preserving freshness and preventing spills during transport. While they are highly secure, they are not technically classified as watertight, so it is best to keep them upright when carrying soups or thin sauces.

No. Because they are made from nonporous tempered glass, they will not absorb odors, flavors, or colors from your food. This makes them a great choice for storing pungent ingredients like garlic, onions, or tomato-based sauces.

Yes, the bowls are designed with a stackable profile to help you maximize storage space. They nest efficiently in your cabinets when empty and stack securely in the freezer when filled.

Duralex tempered glass is engineered to be resistant to thermal shock, meaning it can handle temperature changes better than standard glass. However, it is always best practice to avoid extreme, immediate temperature jumps—such as moving a frozen bowl directly into a preheated oven or onto a hot burner.
