Brushed aluminum mobile suspension ending with three glass globes. Adjustable wire height, maximum 250cm. Globe diameter: 18cm. Around 1970-1980. The rubber sheath of the wires is a little cracked on the top inside the cache, visible in a photo, it does not prevent the proper operation of the suspension and it is not dangerous, nevertheless I can put new wires do not hesitate to report it to me in message.
