These three guys are supposed to surround an umbrella pole, but this small table doesn't have one. My larger table with an umbrella is glass, and I have been afraid to put something as heavy as these frogs on it, for fear of breakage. These were given to me by the friend I re-posted about after my trip. They are heavy metal, of some sort, and should last forever, even though they show signs of weathering. I think they could hold a gazing ball. Wouldn't that look good?
