I fell in love with the product image and bought it. When it arrived, I was surprised to find that the glass part of the aurora bore completely through. I had thought that the glass was embedded in plaster. So, when you place it on a white desk like in the product image, the aurora shines through in various colors and it looks beautiful. However, if you place it on something dark, only the bottom shines through, and the roughness of the plaster, such as the protruding plaster, and the non-slip sponge attached to the back also shine through and stand out in a bad way (left). For now, I've covered it with kitchen paper on the back to disguise it (right). I think I'll paint it white with paint at some point.
