It works but I find it gets pretty dirty on the bottom of it. I’m not sure how but I have to clean it every so often

Sharp Edges.
Color: Gold
Pretty Appearance, BUT the base is very thin and RAZOR SHARP. I almost sent it back, but I had matching gold border tape which I added to it to cover those sharp edges.
