to see or not to see by pizzinelli bruno from italy

A new door that closes the way between two rooms and in the same time makes possible seeing or not through it.
A combination of glass/painted or natural wood and glass/metal, depending from the patterns.
This innovative type of glass is on sale from some times, marketed by Saint Gobain (Vision SGG Priva Lite), and has the extraordinary capacity of being transparent or opaque, thanks to the passage of the 110 V current: just a click to have more privacy!
