Tumbled flagstone is created by rounding sharp edges off and creating manageable-sized pieces.
The result is a very durable 5 to 8-inch-in-diameter, real fieldstone veneer, that's also real, all the way through.
If you want a veneer that is readily available, doesn't scratch, melt or float, purchase real tumbled veneer.
Stop waiting weeks on end for fake stone, get real stone in days, not weeks.
