The OXO Good Grips Twist and Stack Container 5-ounce 3-pack is the long-lasting leakproof, stain-resistant storage you've been waiting for. These durable, leakproof, stain-resistant containers are perfectly sized for any task from meal prep to storing leftovers to taking food on-the-go. They are uniquely stackable and storable food containers to maximize space in the fridge or pantry - lids stack neatly on top of one another and containers nest inside one another so clutter is eliminated. The lids are universal - they fit each container so there's no more searching for the right fit. (Except for our five-ounce containers - those lids are smaller.) These containers feature twistable lids which have a soft touch grip, so the containers open easily and keep food intact. The gasket inside the lid ensures a leakproof seal. This is leftover storage that's built to last - better than those deli containers or packaged food containers. These durable containers resist staining and warping - so they last for the long haul. Containers are top-rack dishwasher safe - but remove the gasket in the lid for deep cleaning. Note - don't microwave with the lid twisted on. OXO Twist and Stack Containers are available in 5-ounce, 12-ounce, 20-ounce, 32-ounce and 40-ounce sizes.
