The OXO Good Grips Twist & Stack Containers 12-ounce 2-pack are the durable, leak-proof and stain-resistant storage option you've been waiting for. These durable, leak-proof and stain-resistant containers are the perfect size for any task, from meal prep to leftover storage to takeout. They are uniquely stackable and storable food containers that make the most of space in the fridge or pantry the lids stack neatly on top of each other and the containers nest inside each other to prevent clutter. The lids are universal and fit any container, so you don't have to search for the right lid. (Except for our 5 ounce containers, these lids are smaller.) These containers have twist-on lids with a soft grip so the containers are easy to open and the food stays intact. The gasket in the lid provides a leak-proof seal. This is a leftover storage option that is designed to last longer than those deli containers or packaged food containers. These durable containers are stain and deformation resistant so they last a long time. The containers are dishwasher safe, but the seal in the lid should be removed for thorough cleaning. Note: Do not put in the microwave with the lid on. This 2-pack contains: two 12 oz/355 mL containers. OXO Twist & Stack containers are available in 5 oz, 12 oz, 20 oz, 32 oz and 40 oz sizes. BPA-free, dishwasher safe, leak proof, microwave safe, freezer safe.
