<p><b>Keep food fresh, and delicious with an insulated bento lunch box from Lille and make every meal more enjoyable! </b></p> <p>Please note that this is not an insulated lunch box so it can only keep your food warm for 1-2 hours. But please be aware that there a couple of things will affect the insulation: (1), the amount of the food in the lunch box. If the food is less than 3/4 of the lunch box, it may reduce the insulation capability. (2), the original temperature of the food put in the lunch box needs to be high enough. </p> <p><b>Product Details:</b></p> <ul> <li> </li> <li>Food-Grade Safe Plastic, Premium Stainless Steel SS304 </li> <li>BPA Free, Non-Toxic </li> <li>Leak-Resistant Seals </li> <li>Available Colors: Blue, Gray and Green </li> <li>Satisfaction Guaranteed </li> </ul> <p></p> <p><b>Useful Tips: </b></p> <ul> <li> (1) The clips on the 4 sides are easily to be opened and closed, so please DON’T pull too hard. </li> <li> (2) Please ALWAYS open the tiny valve on the lid first to release the pressure before opening the lunch box to avoid damage to the handles. </li> <li> (3) Please DO NOT use it in the microwave or dishwasher. </li> </ul>
