STORY / ZIREL

A fun challenge intended for adults

Zirel is simply unsolvable.
The solution is not included.
Zirel lets you enjoy the time spent on a challenge.
Impossible to tell the front from the back because both sides have a mirrored finish!
The pieces are irregularly shaped.
Thanks to its precision design, everything appears to fit but there is only one solution.

Zirel is made possible because of its gaps which are narrower than a single strand of hair

The strength of Iwai Press lies in its techniques to create these kinds of clearances.

These 0.002mm gaps, which cannot be seen with the naked eye, can be experienced with Zirel.
