AC01/03 oil and vinegar set, 1984 Stainless steel, glass, 10 1/4 x 6 5/8 x 6 5/8" Manufactured and lent by Alessi   Castiglioni observed that the lid is usually the most troublesome part of oil and vinegar cruets. Once it is taken off, no one knows what to do with it. He thus left the lid hinged to the bottle and provided it with two big metal ears that work as counterweights. The ears keep the lid in a horizontal position-open while the liquid is poured, closed when the bottle returns to an upright position.
