This is a neat little case for a digital camera. It has a hard surface on the front and back, but elastic on the sides. And the top flat holds in place with a magnet. A great way to keep your camera (or anything else) protected while being able to have very quick and easy access to it.
It has a hook on the back, and also a strap you could put a belt through.
Internal dimensions are approximately 4.5" tall by 2" wide by 7/8" thick. You could potentially squeeze something larger in. But its not going to fit a modern smart phone very well.
