Made in a mould (the seams reaches all the way to the lip) this square bottle screams 1970s/80s. It is not square, the shape is irregular - and the surface looks as if it was blown in a fine wire mesh.
The colour is blue with clear streaks (or vice versa). The 'rustic' aspect has been designed and engineered, obviously. Do I hear bids for Scandinavia or for Italy, for Belgium or for Spain?
