Made from printed MDF board. 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 as well as hanging on a long cord. To install simply slot into the batten and screw the collar in place, then reattach your lightbulb.
 
This shade features our click together design, once you assemble the shade it will not come apart again. LED light bulbs are recommended with these shades.
