This lovely and unique effect was invented by the Dutch Magician Dick Koornwinder in the 1960’s and you can read about the original version here. Tenyo is the only company that Mr. Koornwinder has officially licensed his creation to, regardless of all the versions you might have seen.
Tenyo’s version is different from the original because it has a locking mechanism with a memory, which adds a new dimension to an already perfect effect.
