## Features

- ECO-FRIENDLY 304 FOOD-GRADE STEEL: Built from good quality food-grade 304 stainless steel as an ecofriendly replacement for plastic bento boxes. BPA-Free, PVC-Free, phthalate-free, lead-free, and nothing that leaches into your food. Lower carbon footprint than plastic over its lifetime. Ships in recyclable, plastic-free packaging with carbon-neutral delivery.
- REDESIGNED SILICONE SEAL FOR LEAK PROOF PERFORMANCE: A redesigned silicone seal sits between the lid and the body, sealing soup, curry, dressing, yogurt, and oily sauces inside the box even in a backpack or messenger bag. No glue is used to attach the seal, so it pops out for cleaning and pops back in without tools. A bonus replacement seal ships in the box for free, so the lid can stay leak-proof for years.
- LEAK PROOF SEAL, DISHWASHER SAFE: The outer silicone seal is fully leak proof in all directions. Body and dividers are dishwasher safe. Hand-wash the lid in cold soapy water so the silicone seal lasts longer. If the seal pops out of the lid in the dishwasher (the hot water expands it), wait two minutes for it to cool and snap it back in. Internal dividers are splash-resistant but not individually sealed, so wet and dry foods can share the box without mixing flavors.
- 50 OZ MEDIUM, 3 COMPARTMENTS, ADULT PORTION SIZED: 50 oz (about 6 cups) of food across 3 fixed compartments. Outer dimensions: 8.25" long, 5.5" wide, 2" deep. Fits inside a standard insulated lunch bag, backpack, and most messenger bags. Adult-portion sized, large enough for a hearty lunch with sides, small enough to not feel oversized in a kid's backpack. Recommended for ages 3 and up.
- LIFETIME WARRANTY & HUMAN SUPPORT: We stand behind every box we ship. If anything ever goes wrong, message us through desertcart and a person from our team will reply within one business day with a free replacement, no receipt required. Hand-wash the lid for the brightest finish over time. No freezer (the steel can crack).
