This is an audio-technica AT2020 condenser microphone. It comes with a bag. As a bonus, I'm including a shock mount (actually used with the AT2020, it was included with the microphone arm). This is just a bonus. Please let me know if you don't need it. It was stored in a bag with a desiccant and kept in the microphone bag. Operation has been confirmed, and I believe there are no issues with the sound.
