Abstract: The present invention relates to a storage device for use with a carrying case, and having an aperture therein adapted to receive a handle or strap of the carrying case. The device may also have attachment devices enabling the device to be carried separate from the carrying case if desired. Side body portions of the device have compartments that are adapted to receive, store, and carry items of various sizes. These compartments may be lined with material to protect or enhance the items contained therein. Optional straps may extend from the bottom edges of the side portions in order to attach and secure the device onto a carrying case.
