You are purchasing this exact box. 
The SENTINEL is a classic dice box that is designed to carry multiple sets of dice in a wide range of sizes. Designed with extra depth and width, the SENTINEL can even secure a small mini. The SENTINEL is approximately 8 7/8" x 1 7/8", and 1 3/4 " easily fits larger dice.
 
One of the features we LOVE about the SENTINEL is that it fits perfectly in our TITAN tray for storage and transport. In fact, you can carry up to three SENTINELS in the TITAN tray, and they look awesome sitting on a shelf for display while you're waiting for your next gaming session.
