The OXO Good Grips Prep & Go 20-Piece Set has everything you could possibly need for a week’s worth of meal prep. There’s one container that’s perfect for salads, with a removable tray to separate wet and dry ingredients until you’re ready to mix, plus a dressing container; a 3.3-cup container for soups, pastas, and more; a berry container with removable colander for rinsing and storing fruit; a divided container for bento-style meals; two snack containers, and two extra Condiment Keepers for dips and sauces. The bigger container lids have silicone gaskets and locking clips and the smaller ones simply twist on—and they’re all leakproof. For a secure seal, press firmly in the middle of the lid, then engage the latches; you'll hear air being released as you press the lid down. Once you’ve released all the air, lock the latches on the side of the container to seal. To replace the gasket, press the four corners down, then press the rest of the gasket into place, ensuring the gasket is pressed down fully and evenly. OXO Prep and Go Containers stack neatly on top of each other for efficient and tidy storage either in the fridge or in your cabinets. Although it looks like a sleek, ceramic container, it’s actually a much lighter, BPA-free, durable alternative to single-use plastic. Dishwasher, freezer and microwave safe. The containers are also odor- and stain-resistant, and shatterproof.
