Very cheap, unsteady. Thin material, feels like it will snap with very little pressure. Does not stand up well, so when I place jewelry on it (2 very small pendants on thin solver chains), it tips over, making it not very functional or practical. It also is short, so even short chains fall onto the table (no tray below). I could have gotten a better one at Five Below for less. Really disappointed.
