Kids Konserve KK097 Insulated Food Jar, 12oz, Ocean KEEPS FOOD HOT OR COLD FOR HOURS: Our food jars keep pre-heated food hot up to 5 hours, and pre-chilled food cold up to 8 hours (and often longer depending on the starting temperature and outside temperature). GREAT FOR FOOD FROM SOUP TO SMOOTHIES: Our food jars keep food hot or cold for hours. Pack soup or chili in the morning, and lunch will be steaming when you are ready to eat. Pack smoothies, pasta salad or yogurt and it stays cool until lunchtime. KEEPS TEMPERATURE YOU STARTED WITH: Similar to a thermos, insulated food jars are designed to keep the temperature you start with, so we recommend pre-heating by pouring very hot water inside and letting sit for a few minutes before adding. FUNCTIONAL & PRACTICAL FOR THE WHOLE FAMILY: Our products for kids and adults, ideal for school lunches, work, travel, picnics, takeout, and family leftovers. All products are free of BPA, phthalates and lead. Dishwasher safe. Easy to pack and store. DOING OUR PART TO PROTECT THE PLANET: We believe that small changes have a huge impact. One reusable solution can save thousands of single-use plastic bags, containers, bottles, straws and utensils from our oceans and landfills.
