Thermoses keep drinks at the right temperature, making them useful at work, while traveling or on a walk. The range includes 0.35, 0.5 and 1 liter models, from compact everyday flasks to larger sizes suited to a family picnic. A small thermos fits easily into a bag, while a one-liter model holds enough tea or coffee to share. At home, brew tea in one of our ceramic teapots, and when you need to pack lunch or snacks, use glass containers with lids.
