The body of the jug - a double-walled vacuum body - is made entirely of stainless steel. This means that this thermos jug firstly does not have the usual breakable tempered glass insert and secondly does not have any plastic screw-on parts, while maintaining the same insulating performance. It is manufactured for the catering trade and therefore meets the highest standards in terms of material and usage properties (never breaks, can always be put in the dishwasher). With an overlying stainless steel lid without a seal: on the one hand, this reduces the heat retention time slightly, but on the other hand ensures that the lid lifts automatically when pouring; the pressure equalization noises that can be annoying on official occasions are completely eliminated.
