Vintage 70s chandelier in smoked glass and brass

Chandelier found in a flea market recently, the favorite is its smoked glass which has no scratches whatsoever! The glass has no pattern and can therefore be timeless. A chandelier has a cable where you can see the wire (adjustable. I don't know, I didn't dare pull it) the chandeliers are slightly chipped. The shape is quite original, because it is square and measures 11 cm at the top and at the bottom the dimension widens to 21 cm.
