Made from printed MDF board and an acrylic ring that is screwed into your existing light fitting. Comes flat in a box with instructions for you to assemble.
The shade is special, Chris has designed it so the pieces are flat at the top where the light fitting is attached. The idea behind this is so you can hang it flush against the wall rather than have it hanging on a long cord.
Approx 280 high by 330 wide when assembled.
