Celsius is a comprehensive range of stainless steel thermal vessels for hot and cold drinks, comprising nine sizes of double-walled cups, vacuum insulated flasks and serving carafes, ranging from 0.25 to 2 l capacity. While the vessels can be used for any beverage, they have been particularly designed with tea in mind and therefore the cups include internal tea strainers for loose leaf brewing. The cups are also included with the flasks, where they magnetically attach upside-down to the plastic screw cap, which in turn has an intuitive push button opening mechanism and an innovative 360º pouring spout.
