The EM77 vacuum jug with the unique rocker stopper was created by the Danish designer Erik Magnussen and is produced in Denmark since 1977. Today the vacuum jug is a design icon around the world. The jug holds 1 l. and can be used for coffee and tea. The insulating glass insert keeps the liquid hot for hours - or cold, if the jug is used for e.g. ice tea. Besides the rocker stopper it has a screw cap for picnics and transportation of liquids.
