Reebok wanted something that could house a CD, give lots of area for graphics AND demonstrate its pump technology. This one took a bit of head scratching, but we came up with a way of attaching a spinning knob (like on the sneaker) to the front of a CD sleeve. The piece is shipped with all of the flaps folded in and as the user rotates the knob, the flaps pop opened one by one, revealing the copy inside. Once fully opened, the CD pocket is revealed.
