27. Ronan & Erwan Bouroullec (1971- & 1976-) (FR)

The Erkkeri series (or Ruutu Limited Edition) was handcrafted using the mouth-blowing technique at the Iittala glassworks. The series was produced exclusively for that exhibition and is no longer in production. Only a few pieces of each color were made; in total, there were perhaps around twenty pieces.
