Helge Thun's Duplicate Principle was kept underground for many years. In 2026, Vanishing Inc. published Evidence of a Well Spent Life where Helge revealed the inner workings of his most closely guarded secret.

Not only will you learn Helge's work on the method, but he teaches you multiple applications, including a killer Brainwave, an impossible Torn and Restored, and one of the strongest and most fooling Traveller's routines we've ever seen.

You can now get these refill packs of the gimmicked cards, meaning that you can perform these amazing routines at any time.

Each pack contains:

• 10 Red Kings
• 10 Black Kings

Please note that this product does not include any instructions. You receive the specially printed playing cards only.
