This is a cover for a light bulb from a hallway about 30 years ago. When the light was turned on, the unevenness of the glass created beautiful light patterns on the wall. When the light fixture itself broke, I wanted to use this cover, but the size of the socket was different, so I gave up and kept it. There are three of them, but this is a listing for only one, which I have cleaned and inspected. Weight: Approximately 1 kilogram Diameter: Outer approximately 8 cm Inner 6.7 cm Height: 16.5 cm Width: 14 cm These are approximate measurements. I think it can be used as a lampshade or a vase. There are no noticeable scratches or damage, but it is an old item, so there may be some scratches if you look closely. Please understand that this is a used item before purchasing.
