Design by Erik Magnussen, 1977. By Stelton. Erik Magnussen's vacuum jug with its unique rocker stopper was introduced in 1977 as follow-up to Arne Jacobsen's Cylinda-Line. Just like Arne Jacobsen's design the stringent cylindrical shaped, graphic appearance of the vacuum jug expresses a minimalism and functionality that remains ahead of its time. With over 30 years of success, the line is celebrated by Stelton with release of six limited jubilee jugs, for which this timeless classic received the Danish Design Prize 2007, the only product ever receiving this prestigious award twice.
