The thermos inside OmieBox can keep food hot for up to 4 hours - just make sure to preheat it with boiling water! Here are a few tips for success:⁠ ⁠ ✨ Make sure the water is boiling (at least 100 degrees Celsius) when you fill the thermos.⁠ ✨ You can put the lid on top, but don't screw it in - the hot water will make it difficult to unscrew.⁠ ✨ Let it sit for at least 5 minutes.⁠ ✨ Heat up the food hotter than you would want to eat it. The hotter it is when you pack it, the warmer it will be a few hours later!⁠ ✨ Pack the thermos as full as you can. The more densely packed the food, the longer it will stay warm.⁠ ✨ Close the lid immediately to keep the heat in.⁠ ⁠ Some foods stay warm longer than others. Keep this in mind when deciding what to pack for lunch! ⁠ ⁠ What are your favorite hot lunch ideas? Tell us in the comments 👇️⁠ ⁠ #omielife #omiebox #omie #omielove
