The OXO Good Grips Twist & Stack Container 12-Ounce 2-Pack is the durable, leak-proof, and dirt-resistant storage solution you've been waiting for. These containers are the perfect size for any task, from meal prep to storing leftovers to taking food on the go. They are uniquely stackable and space-saving food containers that make the most of refrigerator or pantry space. The lids stack neatly on top of each other, and the containers nest inside one another to avoid clutter. The universal lids fit any container, so you no longer have to search for the right lid (except for our 5-ounce containers, as those lids are smaller). These containers feature twist-on lids with a soft grip, making them easy to open while keeping food intact. The seal in the lid ensures a leak-proof closure. This is a storage solution for leftovers designed for long-lasting use – better than deli containers or packaged food containers. These durable containers are resistant to dirt and deformation, ensuring they last a long time. The containers are dishwasher safe, but for thorough cleaning, the seal in the lid should be removed. Note: Do not microwave with the lid on. This 2-pack includes two 12 oz/355 mL containers. OXO Twist & Stack containers are available in sizes 5 ounces, 12 ounces, 20 ounces, 32 ounces, and 40 ounces. BPA-free, dishwasher safe, leak-proof, microwave safe, and freezer safe.
