Very rare piece from the blue marble collection from estee lauder. This was brought out in the late 1990s and early 2000s. Most of the items with the blue marble were part of large gift sets.
This is the makeup / cosmetic brush holder.
It has an asymmetrical design. The tallest point on this cup is approx 3".
It was part of an estate collection in an unused gift set. Some of the items were not usable so selling as a stand alone item.
