Shishi is a Norwegian-Estonian joint venture established in 1998 by Linda Johnsen, Lilli Bendriss, Taivo Piller and Mart Haber.
 Initially, the main emphasis was on self-created vases and artificial flowers, as both Linda Johnsen and Taivo Piller are internationally recognised florists, champions of their respective countries on numerous occasions and representatives of their countries in European as well as world championships; both have also been jury members in international contests.
