The set of three glass buoy floats w/ rope measures 3"Dia. x 4"Dia. x 5"Dia. From smallest to largest the floats are purple, green & blue in color. They are the perfect piece of nautical decor. In years past glass floats were used to keep fishing nets from sinking. They are rarely used today but are a pleasant reminder of the way things used to be. The floats are encased in decorative rope nets that are used for hanging. They make a great gift and impressive decoration.
