Bernadette Deddens studied Product Design at the Academy for the Arts in Arnhem and Design Products at Royal College of Art in London. Bernadette views the accessory as a prop that can add small-scale drama to daily life. In 2009 Study O Portable was founded by Bernadette Deddens and Tetsuo Mukai. S.O.P. designs and produces accessories and other portable objects. We perceive accessories as props, that can subtly influence our behaviour. The collections consist of made to order and ready made items, both presented spontaneously as they materialise, and as complete collections.
