The blue glass float w/ LED light measures 5". The blue float is encased in a decorative net and has a LED light inside that lights up. 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. This item will add a definite nautical touch to wherever it is placed in and is a must have for those who appreciate high quality nautical decor. It makes a great gift, impressive decoration and will be admired by all those who love the sea.
