Paro is the fruit of a careful study of glass shaping and production - glass blowing, break off, welding and grinding – regarding fine lead crystal. The magic of master glass makers produces a drinking glass with two different capacities.  Two cones, each inverted in respect to the other and joined near their vertexes as if they were sliding past each other, alternately become base or container in an endless game of right side up and upside down.  Price listed is for one glass.  Manufactured by Danese Milano.Designed in 1983.
