A curio is a predominantly glass cabinet with a metal or wood framework used to display collections of figurines that share some common theme. Most curios have glass on each side or a mirror at the back and glass levels to show the entire figurine. A curio prevents dust and vermin from destroying the value of the collection. Curios are also used to display single crafted dolls. A curio is different from a display case, in that while a display case is usually horizontal to display jewellery for sale on top of a felt bottom, a curio is vertical to show standing items and usually has no bottom lining.
