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.
PRODUCTION PROCESS
Zirel cannot be mass-produced.
Each puzzle is a one-of-a-kind item that takes time and effort to produce piece by piece only after an order is made.
It requires about 10 processes over 72 hours to complete.
Iwai Press brings together several techniques to meticulously craft it.
Our designers create a rough outline
The design is then drafted into CAD data
Warping and other distortions of the quenched industrial stainless steel are flattened and hardened in a polisher
When the stainless steel is ready for processing, its pieces are cut using a brass wire with a thickness of 0.2mm in water.
(Processing time for one puzzle is about 10 hours)
After the cutting, each piece can have burrs about 0.05mm in size. So they are further polished while a craftsperson inspects its profile by eye
After the profiles are polished, metal powder is removed and the pieces are further polished by blasting them with diamond particles
Final Polishing on a Precision Grinding Machine
After assembling the pieces, the final polishing is performed on a precision grinding machine and with our craftsmanship until the spaces between the pieces become invisible
After the final polishing, buffing is done to give it a mirrored finish and glossy look that is the real appeal of Zirel
