Its double-wall technology with an intermediate vacuum allows it to maintain the temperature of both cold and hot liquids for a long period of time (approximately 24 hours). Thanks to the lever on the lid, you can open the vacuum seal with one hand and serve directly. When you release the lever, it will reseal. Capacity of 1 liter: this stainless steel jug has a volume of 1 liter for approximately 8 cups of coffee, tea, etc. Easy to clean: the wide-mouth opening design allows it to be easily cleaned with a damp cloth or sponge.
