I purchased this from MUJI around 2011 and used it. I'm selling it now because I no longer need it. The shade has a diameter of approximately 26cm and a height of approximately 20cm. It's lightweight, so I believe the material is not aluminum. The socket size is E26, and a light bulb is not included. There are no noticeable damages, and I think it's in good condition, but there is some overall wear and tear. Everything in the photos is included. This is a used item, so please refrain from purchasing if you are concerned.
