Teacher: Now, understand the problem? Solve this instance: Works great and compact and convenient. The detachable lanyard is nice for when I don't want to carry my pack with me. I don't see myself using the white and black cards too often, but they're nice to have. The cards are of a nice quality, thick enough to not bend accidentally when in the camera bag.
