More information, please visit our website: www.markedcards.cn it feels and rolls exactly the same as normal dice. what we did is cut it into half and install a small wireless device at center, then resume its original shape. another wireless coil is installed in power board under the table. then you can control the dice to get the number you want
power board dia 10cm-60cm, maximum scope of the electromagnetic field dia 100cm
We have the dices of any sizes. you can control one of them or control several of them. 12 dices in a set with various sizes.
