Luminaire suspendu géométrique unique à 1 lumière Mara

I ordered 4 of these. Packaged well, looked amazing and seemed of good quality until the electrician started hanging. The cords could NOT be adjusted. All the parts were there to try to adjust but cord would not move through the bolt at all. Electrician worked for hours to try to make it work. Very disappointed as the light fixture was beautiful but had to be returned. Buyer beware !!!
