This Mic holder is for the TONAR Mic that you can easily Slide into the part and have the part fit perfectly with your 24in iMac. It holds on the top right of your iMac and has a perfect angle for you so you can talk without reaching out for the mic. There is a hook on the back side so once you put the cord through the back, all you have to do is wrap it around and secure it so it does not slip.
