I bought a high-quality wooden dressing table, Italian made, but I didn't need its mirror because I have a larger one...
The mirror has a heavy wooden backing and is fitted with three metal rails that you can use to hang it or attach it to a dressing table or drawers.
Its size is as shown in the picture, I expect it to be one meter by one meter.
It has been wrapped in plastic since I bought it for preservation, and I apologize for not removing the plastic as it is clear.
