New and Improved!!  This very cool Mug actually will hold a cup of coffee or other liquid while storing your valuables in the bottom of the Mug.  You can store stuff in the approximately 4" x 3" storage area (see enlarged picture for open mug).  The lid for the top of the Mug has a locking mouthpiece to drink your coffee through.  The top of the mug also screws onto the base for more discretion and safety!  The Mug is approximately 6 2/8" tall, 2 1/2" at the base and 3 2/8" at the top.
