If you are doing a live sale with many items, these are extremely useful. Each item is half of a credit card with a hole in it to put over a hanger. The tag has the number written normal on one side and reverse on the other so the viewer will see the correct number depending on how the camera is recording the video. They come in with 2 attached, so you need to separate them first. Use caution to make sure you separate them at the marked line.
