Meal preppers, these Sekonow stainless steel containers are seriously durable and practical! Made from 18/8 (SUS 304) stainless steel, they won't rust, stain, or absorb odors like plastic containers often do. The three separate compartments are perfect for keeping foods from mixing together - think veggies in one section, protein in another, and carbs in the third. Each container holds 600ml/20oz total, which is plenty for a satisfying lunch. The leakproof lids with silicone seals and four snap locks mean you can pack saucy foods or dressings without worrying about spills in your bag. They're stackable to save space in your fridge or cabinet, and the compact size (10.4x4.3x2 inches) fits perfectly in most lunch bags. You can put the steel base in the dishwasher, freezer, or oven (though the lid is hand-wash only and not microwave safe). Whether you're packing lunch for work, school, picnics, or travel, these containers make meal prep so much easier and more organized. The 4-pack gives you plenty for rotating throughout the week too!
