This cooler not only looks good, but is very well made.  The bottom and sides are a full 1 inch thick and the lid is actually 2 1/4 inches thick, and makes a very tight seal.  The inside is a smooth white plastic surface with dimensions of 10 inches in diameter and 10 inches in height, subtract 1 1/4 inches from the lid inserted depth.  For me, this was a perfect volume and size as the overall height is 14 inches.  Very nice cooler, I'm very happy with it.
