The OXO Good Grips 12-Piece Twist & Stack Container Set 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. This 12-piece set includes: two 12 oz/355 mL containers, two 20 oz/592 mL containers and two 32 oz/946 mL containers. OXO Twist & Stack Containers are available in 5-ounce, 12-ounce, 20-ounce, 32-ounce and 40-ounce sizes. BPA free, dishwasher safe, leak proof, microwave safe, freezer safe.
