This is a set of 9 pieces I belive they were taken off a star topper no longer working. There are 9 of them, none broken, cracked or missing parts. The diameter is 1 1/4" outside point to outside point. The inside of diameter at the bottom, what size your Bulb will need to be is 3/8 bigger than bulbs on a string of lights. If they are too big but you have a flat surface, you could glue them on.
