The Shure SM7B Close-Talk Windscreen is a product designed for use with the Shure SM7B dynamic microphone. It is a windscreen that helps to reduce unwanted noise and plosives during close-talking applications. This product is made by Shure, a well-known brand in the pro audio equipment industry. The SM7B is a popular model of dynamic microphone used in musical instruments and gear, as well as in broadcasting and podcasting.

Again, this is just for the windscreen (no microphone) and the box/info. with it.
