This is a used item. Please refer to the photographs for better description. I do not see anything to bring to your attention I feel it’s in very nice shape nice bright dark blue crisp, white lettering some staining. I do not know the age could not find anything about it. The mirror is in great condition in my opinion if you have any questions, please ask. The measurements are approximately. 3 1/4 inches hard to get the dimensions on the depth / thickness 1/4 inch I do not see any cracks in the cover holding the rock salt in place.
