Unleash the power of the dark side when you get this Sith Holocron! 
When a Kyber Crystal (sold separately) is inserted into the cube you can unlock colors, sound effects and even authentic film dialog from characters such as the Emperor and Darth Maul and many more. 
The colors and sound effects you hear depend on the color of the crystal inserted. It is rumored there are other surprises in store for those curious enough to experiment with the pyramid and the light side Jedi Holocron. 
Pyramid measures 4.5 inches high. Corners turn and center opens. Powered by a rechargeable battery and comes with a USB power cord and storage bag.
