I purchased this a few years ago and have kept it unused. The color is green. When you fully open the side zippers, it becomes two feeding bowls. The inside uses water-resistant polyethylene, so you can put not only your dog's food but also water in it. After your dog has eaten, you can fold up the used surface and close the zipper, so you don't have to worry about getting your bag dirty. Also, it can be washed with water (by hand), so you can always keep it clean. It's compact and lightweight, about 3cm thick even when folded. It comes with a carabiner, so you can easily attach it to a bag, and there's a loop on the back, so you can also attach it to a belt. Diameter: 12cm
