Do you find it annoying when playing a board game and the dice roll off the table, knocking over all the pieces? Or when you suspect a friend is cheating by manipulating the dice? All these problems are solved with this mini kit. Unlike its little brother (the MK109), you can activate this die not with a push button, but simply by shaking it. The die has seven bright red LEDs; shake it before use. It uses a lithium battery (not included).
