They look flat and useable but once placed in water they swell!
I was not sure what these were as they do not look like the listing. I thought that I had been ripped off. But we gave them a chance and placed in hot tub and to my surprise they expanded to normal size. The picture shows what I got and we included a follow up picture from hot tub. Don’t know how well they work so that is why I am only giving 3<br />Stars.
