Review on 🥣 Stainless King Vacuum-Insulated Food Jar, 24 oz, Midnight Blue - THERMOS by Erica Rogers

If you want to keep dry/non-liquid food warm, YOU MUST PREHEAT IT! Pour boiling water and leave for a few minutes before adding food (heat food before eating). Don't buy too big either! In order for this to work as well as possible, you need to fill it up completely so as not to lose heat to the air space. I usually fill it up around 5:30 a.m. and eat lunch from it between 11:00 a.m. and 12:00 p.m. It holds heat well enough that after about 6 hours I usually have to blow on the food to cool it down as I eat. Didn't get a chance to eat lunch yesterday - my food spent 12 hours in a thermos and was still 130 degrees Fahrenheit when I opened it. I definitely recommend this product.
