Often they had an attached chain so as to be suspended from a bracelet, chatelaine or finger ring (such as one worn by Queen Victoria).Some examples have a locket at the bottom, and rare examples are in the form of a small powder horn (sometimes called a 'bugle') with a built-in whistle.Vinaigrettes were made in France, Switzerland, and England.
