This company began in the late 1920s as Monocraft Products Co. of Providence, R.I. This piece is c. 1955 and one side edge has small inset piece of metal with a copyright symbol and their "Monet" name. The thick red plastic band measures about 1" across with a thickness of the material varying from as much as .5" down to 5/16". The material is also molded so that the edge where the material is thinnest has an overall shape slightly concave. On the interior surface is black/silver sticker, small edge nick and with very slight trace of wear to the color, reading "Directives by Monet" plus what seems to be a model number "07137" and what seems to be a price "20.00." The dark red plastic is accented by a cream colored circle on one side and a cream colored vertical stripe on the opposite side. A very stylish piece of 1950s jewelry. Exc. and displays Mint.
