Our advanced triple-layer insulation technology keeps food hot for 4+ hours after packing. Most users enjoy perfectly hot meals up to 6-8 hours later depending on ambient temperature and initial food temperature. For optimal results, pack foods as hot as possible directly from cooking.

Yes, absolutely! Bento Box uses military-grade sealing with a four-point locking system that has been tested extensively with water, soups, and sauces. When sealed properly according to instructions, it's guaranteed 100% leakproof. Our innovative design features visual indicators to confirm proper sealing, so you always know your food is protected. We've tested it in extreme conditions and never found a single leak when sealed as directed.

Bento Box is made from premium, food-grade, BPA-free materials that are completely safe for your health and family. We use pharmaceutical-grade silicone seals and high-quality stainless steel or eco-friendly plastic depending on your choice. All materials meet or exceed FDA food safety standards. We don't use any harmful chemicals, plasticizers, or toxic compounds. Your safety is our top priority.

Yes! All compartments are completely dishwasher safe on the top rack. However, we recommend hand washing the seals to extend their lifespan significantly. Silicone seals can last longer when hand washed and properly dried. The entire unit, including lids and seals, can be safely washed in warm water with mild soap and dried thoroughly before storage to maintain optimal performance.

You can pack almost any food! Hot soups, curries, rice, vegetables, proteins, pasta, sandwiches, and more. The leakproof design means even wet foods like gravies and sauces are perfectly safe. Just pack foods as hot as possible for maximum temperature retention. You can also pack cold foods if you prefer - the insulation works both ways and keeps cold foods cold too. Avoid extremely hot liquids (above 212°F) immediately after cooking, as they may affect seal integrity.

With proper care, your Bento Box will provide years of reliable performance. Most users enjoy theirs for 5+ years with minimal maintenance.
