A cold day in the mountains or a warm day at the beach, this product will keep you energized all day long, whatever the weather and wherever you go. The Artisan Thermal Food Jar is made from recycled stainless steel and uses 4D Thermology technology for premium insulation, keeping your food warm for 13 hours or cold for 14 hours. Prepare your hearty pasta or refreshing gazpacho in the morning without having to worry about temperature fluctuations for up to 14 hours! Because the jar is leak-proof and packable, you can pack it up and go without worrying about food being in places it doesn't belong at lunchtime. At the end of the day, you can put the food container in the dishwasher for quick and easy cleaning. The design of the Artisan collection is a nod to some of our earliest products made by William Stanley Jr. 110 years ago; you'll recognize it by the cork-embellished, steel-coated stopper.
