Stephen Tucker has a creative force you can always count on, and this mentalism trick that uses simple and attractive objects is truly bluffing!
Shard is very easy to do, no suspicious movements, no manipulation.
The effect is clear, and there is no forcing, the spectator really has a completely free choice, and has no idea of the contents of the box before it is opened.
You can even be blindfolded during the whole tour if you wish; for example, having a spectator behind you covering your eyes with their hands is a really good presentation idea.
Shard comes with specially printed business cards, cases, ring and playing dice (you will need to provide your own coin), and instructions in English, including bonuses.
